Opera does not complete to load the webpage
Hello, many times Opera does not terminate to load the webpage and shows the number of pending elements as you can see in the image. Net settings are as default. I also tried different but nothing changes. This does not happen all the time but frequently.Do you know what can I do?. Thanks.

I "suffered" with this problem for some time and only recently decided to tackle it.
Start with the post below and the 4-6 subsequent posts as to how I finally solved the n-1/n error! I had TWO desktops with the same problem and after I "fixed" the first, the second was easy.

If you do not use content blocker or hosts file and you still get partial loading, look for other blocking sources (like blocks on OpenDNS, router, family site blockers, etc.). Use either hosts file or Opera content blocker but not both for ads -- I found that it could cause conflicts. If you use hosts file, you may be able to find and disable the offending entry. HTTP Sniffers can help detect detect the offending entry. BUT,hey, this is no different than if you had the same problem with hosts file with IE or FF - you have to find the offending entry.
I did not suspect the hosts file because it worked with IE and FF. Well, it is my opinion that it is NOT the hosts files, per se, but is due to the way Opera renders site pages. I found the offending entries and deleted them. BTW, I use HostMan w/a little Local HTTP server to substitute transparent image (or other) for blank spot where ads are removed. http://www.abelhadigital.com/hostsman
Good Luck!

First of all congratulations, I renamed my hosts file and that works for me too, looks like you solved a long time mystery. The strange thing is that I use my urlfilter.ini for add and script blocking and the hosts file to block a few apps from phoning home plus two sites that the ini couldn't block. I am sure I don't block anything on allmusic.com but only after disabling the hosts file does it load properly.
Maybe a bit early to call this a bug in Opera, it could also be my Windos 7 playing tricks, very curious about other peoples experiences!

Nice job for the weekend: going to make a folder with usual suspects and test if the hosts file really makes a difference.

No need to not use hosts file! It's been about a week now and I'm using hosts file. My Opera is screamin'! Trust me: hosts file is an effect of the problem -- along with not having dedicated folder for each Opera version. It really has to do with the combination of the way Opera "reads" pages and the hosts file (and anything that blocks ads, etc.). You have to find and remove the offending entry in the hosts file. I did have to remove a couple of items from the hosts file when I ran across sites that would not completely load (n-1). When I removed the offending blocks, they load immediately. I've used hosts file for years and this is the first time I ran across anything like this. Keep in mind they I did a clean install -- named the folder Opera 11.01. I believe that the automatic update with versions installed over another was a contributing factor.
I don't have any urls in my Opera content blocker (urlfilter.ini). I did run into a conflict of some kind likely due to duplication of some urls; it may be possible to block selective content/sites with content blocker and still use hosts file.
I mentioned that I use HostsMan as hosts manager along with its HostsServer (which replaces blocked ads with one pixel transparent image). So, what this means is that something is provided to replace the ad instead of nothing which then generates the "site not found, "action cancelled." etc messages. Whether that makes a difference on how the page is rendered I do not know, but may. In any case, I use HostsServer to replace those 'site not found' messages and white blank areas. Most times, the pages adjusts to the small image removing the ad space area.
As for poor webcounter scripts being the problem, they would likely be a problem in other browsers. They can be also be blocked with hosts file or custom user javascript file. MVPS hosts file blocks about a dozen or more counters.
bartgzn --
You stated, "I am sure I don't block anything on allmusic.com but only after disabling the hosts file does it load properly." It loads fine here (don't you just hate to read that!). I suspect something is being blocked. Do you use user javascripts? Depending on the script, they could also cause problems. In any case, if you disable hosts and the site loads properly, there is a script on that site that is blocked by an entry in hosts file and causing the hang up. I did a quick look at the source file (allmusic site) and found these:
ads.jetpackdigital.com
ad.doubleclick.net
google-analytics.com
edge.quantserve.com
.scorecardresearch.com
laurel.rovicorp.com
Check your hosts file for each and disable them (# before each entry) or delete them. I think this will solve the loading problem on the allmusic site. Also, if things seem slow you might flush your DNS client service. Use Command Prompt and type: ipconfig /flushdns (press Enter). Tada! Also, if you have a very large hosts file, it can slow things down.
gdveggie --
You stated, "...the final elements that don't load are failing to be retrieved by the site's server (e.g., allmusic.com) from some other remote server (e.g., web statistics counters), sort of a "third-party" element...." True. Really most are "third-party" sources (ads, etc.). Per MVPS site:
HOSTS file can speed the loading of web pages by not having to wait for these ads, annoying banners, hit counters, etc. to load. This also helps to protect your Privacy and Security by blocking sites that may track your viewing habits, also known as "click-thru tracking" or Data Miners. Simply using a HOSTS file is not a cure-all against all the dangers on the Internet, but it does provide another very effective "Layer of Protection".But it is not perfect. Some things, when blocked, causes these Opera (n-1) hang problems. I think this is exclusive to Opera and the way it renders pages sequentially. Counters? It is not only counters but could be most anything that is blocked.
Why not all blocked sources? I think it is a function of the script, the web page design + the way Opera "reads" the page. So, you can use hosts file that blocks 9 ads, etc. on a site but one hangs the loading (n-1). Just remove the offending block from the hosts file, learn patience, put up with the advertisement, and live long and happily thereafter with your screamin' Opera.

Thanks! We seem to meet in the strangest places, doncha know.
Say, I think you use a different hosts file than I do -- hphosts? I use MSVP hosts file because, IMHO, it is updated and tested often. LIke others it block ads, banners, 3rd party Cookies, 3rd party page counters, web bugs -- and even most hijackers (including fake antivirus drivebys). Plus, it is small, ~150kb. Those drive-by hijackers and dump some bad stuff onto your machine. The worst are those fake antivirus pop-ups that take over everything. My daughter had that happen to her while searching and surfing for something for her children. I took me awhile but I cleaned it out and installed Opera while I was at it. Anyway, I digress. The point is that you may not be experiencing any problems is likely due to 1) you only visit this forum and the hphosts site
and/or 2) you hosts file is much different than the MSVP hosts file, or you may not even have a hosts file.
I joke since I have seen your comments when checking problems sites. Do you use anything to replace the action canceled, navigation error, the red-X, etc. the show up in the places that ads were blocked? If you do then it may be that the image fulfills the vacant slot and you never see it or know it is there. As mentioned, I use HostsServer to replace the messages with a tiny transparent image. Some websites use "IFrame" and HostsServer solves the problem and cleans up the page for nice viewing.
Regardless, IMHO the problem is definitely related to how Opera loads the elements given hosts files (and/or content blocker) simply because the n-1 issue never happens with IE or FF. It seems unique to Opera. Is it a bug? Depends on how you look at it since in most cases Opera works fine without hosts file or content blocker. But content blocker is a feature of Opera and can cause the same n-1 problem, it is an Opera issue.
In some cases, when hosts file/content blocker are not utilized, the n-1 hang occurs; the solution is to find the offending javascript, ad source and use a hosts file to block it, thereby permitting the site to load without the offending script. This is site unique due to things like bad scripts. I've not experience this though.
In the majority of cases, the problem occurs due to the offending script or ad IS blocked by a hosts file; the solution is to find the offending source and remove it from the hosts file. I think sibelius mentioned that rebooting seems to work sometimes. Yes, that was my experience also. Clearing private data did nothing but reboots (yes, more than once) somehow forced Opera to "clear the decks" to permit loading of the site w/o hangs. Again, I think it has to do with sequential loading by Opera in some way.
If you have reinstalled Opera into its own folder (i.e., Opera 11.01; d/l Opera to local folder and install from the folder instead of running it as it downloads from the server) and none of this seems to work, I would look for other things that might be a contributing cause although many of these would manifest themselves in IE/FF also. For example, check to see if a site is blocked by your firewall or router. Do you have any kind of adblocking feature on your antimalware/antivirus program? If you use OpenDNS, check to see if you have checked a category of sites to block. If you use Opera's turbo feature, it may make a difference but it does not alter webpages but does compress images so image resolution may appear considerably lower as a result of the compression. Might be worth checking to see how things work with and without turbo. Are you using something like NetLimiter (internet traffic control and monitoring tool. You can use NetLimiter to set download/upload transfer rate limits for applications. Also, what are your max connections server, max total connections settings (Tools-Preferences-Advanced, Network)? Set to default. You can optimize Win XP TCP/IP internet connection with Cablenut (http://www.cablenut.com/); I have custom Win XP css file (if you like a copy, send me email address or whatever). I never leave home without it! :-) As mentioned before, do you use user javascripts? Some are rendered obsolete (broken) with new Opera versions; check for update of the user javascript.
I logged onto this site this morning and saw a lot of white area, noticed that it seemed to stall. I thought, "How wonderful. I get to find another entry to delete in the hosts file." No such luck. It loaded within about 8-10 seconds. It now loads in microseconds. Darn it. No more n-1 hangs. Sorry about that; I couldn't help myself.
http://www.smartplanet.com/business/blog/business-brains/study-cloud-computing-could-help-transform-european-economy/14049/
Well, that's my "brain-dump." You now know as much as I or maybe more.
Like you, gdveggie, "I don't know why I'm NOT having any of the n-1 problems" anymore. (wink-wink)Hope everyone solves the n-1 problem and can enjoy Opera running wild and fast, loose and free, throttle to the max!

6. March 2011, 06:41:51 (edited)
"No, I'm not using a Hosts file at all...."YES! My original suggestion. Definitely no n-1 problems. However, since I've been able use host files. I did not like the idea of not having a hosts file since it has great advantages. No problem using hosts file per upstream comments.
"I can't see any reason a reboot should be necessary. From my understanding, it seems at most, clearing the cache, maybe deleting all private data (?), and restarting Opera should be sufficient. So this puzzles me."True. I have puzzled over this one also. I can't tell you the times I cleared the private data without any help. Restarts work...rarely. Reboots work almost always. Of course, I did this with several sites open; I never restarted with no existing sites open (no tabs). I can only guess that that Opera, as an app, loads clean in Windows and that somehow there is something that effects the way pages are rendered for that session. I simply do not know why that helps. How many times has it been suggested for many apps to reboot...even Windows? Maybe it's like a slot-machine - the marbles go in different slots until a new game (reboot).
I suppose one could install Opera in Sandboxie (great app; run programs in a virtual sandbox environment without writing to the hard drive) to determine what is loaded and where. I leave that for others to pursue. 
UPDATE: Reboots flushes the DNS Cache! See post below: http://my.opera.com/community/forums/findpost.pl?id=8798541
Given that one has hosts files, usually, when a site page is rendered and no response is received from ad server (times out), an error message is loaded (site not found, etc.) or it is simply skipped (block works) and the page loads. For some reason, sometimes Opera waits for the response (no timeout). When Opera is rebooted, it seems to somehow get pass the waiting and moves on, so to speak. However, with Opera some ads just stalls the loading, period. It's lookin' for love in the wrong places (apologies to Waylon Jennings). The solution is to either 1) use something like HostServer to provide that 'love' in the form of a one pixel image. If that does not work, then delete the offending entry in the hosts file.
My only hypothesis (i.e., wild a-- guess), in simple layman's words, is that when scripts requests ads from servers -- and they are blocked by hosts file or content blocker -- nothing is received, it waits (sometimes) for something from the server. That is why I use HostServer -- it provides something to fill that request, a one pixel transparent image. So, until someone explains it I'm stickin' with this as the explanation. Otherwise, I choose to let the mystery be as Iris Dement sang in her song.
"Ever since I started using Opera, I always install each new version to its own folder"That is the best solution! Opera's automatic version updates should do that automatically.
"You mentioned this CSS file...."Sorry, I was not clear. This has nothing to do with Opera; it is Cablenut. "You can optimize Win XP TCP/IP internet connection with Cablenut (http://www.cablenut.com/); I have custom Win XP css file (if you like a copy, send me email address or whatever). I never leave home without it!"
As far as blocking some parts of web pages in content blocker, it should not cause a problem -- in most cases. Want to experience n-1 stalls? Add hosts file (MVSP hosts file) and then surf. Most pages load okay; a few do not. Definitely cause-effect. I tested this on my other machine also. Easy to duplicate. I did it with my laptop also. However, this is not to say the hosts files are THE cause because anything that blocks sites (see my earlier comments) can cause it. Some ISP block certain sites also.
Still no n-1 load stalls here and its been about a week or more.
Ummm.

You may be correct, but I am having a different but related issue at one forum I frequent. For some reason, sometimes that particular forum's pages will take several minutes to load and other times they load in a few seconds. This is when I am using my cellular WWAN card. I have come to the tentative conclusion that the IP address I connect to is the culprit. A reboot will automatically reconnect using a different IP address (of course I can accomplish the same thing with a disconnect/reconnect of the connection), so sometimes this fixes the very slow page loading time of that forum. I have noticed no problem with IP addresses 32.176.xxx.xxx, but oftentimes have problems with IP addresses 166.183.xxx.xxx. Note that other web pages and forums load normally with either IP address. The offending forum happens to be the carrier's forum for my cellular WWAN service!
EDIT: BTW, I am using the openDNS DNS servers, so I don't think this is a DNS issue.
6. March 2011, 05:16:51 (edited)
It is not the hosts file, per se, since they work just fine with IE and FF. IMHO, it really is the way Opera renders pages although DNS resolution can be a contributing factor. If the local DNS cache has stored negative responses or url addresses change then there can be a long delay (inability to connect, etc.). The default time period for keeping an address in the cache is 24 hours. However, this would not be exclusive to Opera; it would also be an issue with IE, FF, etc.
Whether Opera, IE, FF, etc., clearing DNS client service often helps. Use Command Prompt and type: ipconfig /flushdns (press Enter); make sure DNS Client is running when you do this. Large HOSTS file (over 135 kb) tends to slow down the machine. If not on a network (single PC, homeuser), set DNS CLient in Services to Manual. Otherwise, if you find after a period of time that your browser seems sluggish with the DNS Client service enabled you can manually flush the DNS cache.
What's in your DNS cache? Use Command Prompt and type: ipconfig /displaydns (Press Enter).
Yes, it is likely that the DNS Client cache a role in the n-1 stalls. Here is the optimal solution for WINDOW XP:
Caution: If you are not familiar with registry edits, do not do this. Mistakes can lead to total system failure.
Configure the DNS Resolver Cache
A way to minimize problems from the long default wait times that are used for holding data in the DNS cache is to reduce the times (known as Time to Live or TTL). This requires a Registry edit so should be done only by those who know how to restore their Registry. The Registry key that is involved is
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNSCache\Parameters
The binary entry MaxCacheEntryTtlLimit can be used to control how long positive responses are kept. Values are in seconds and the default value in the absence of an entry (the usual case) is 86,400 seconds or one day. If you wish to shorten the TTL, create the entry and enter your preferred time in seconds. Most PC users will probably not gain much this way, however.
Negative responses are another story. I often encounter Web sites that do not respond immediately but which are available after a short wait and a retry. A wait of five minutes would be neither convenient nor necessary. I see no reason to store negative responses in the DNS cache and I have tweaked my own Registry to prevent them from being entered. In this case create a binary entry for the above Registry key and name it NegativeCacheTime. Set the value to "0" (zero). If you prefer to keep the negative responses, but with a shorter TTL, enter the appropriate number of seconds. The default TTL is 300 seconds.
Defend Against Responses from Non-Queried Servers
If its settings are left alone, the DNS cache will also accept responses from servers that it never queried. In other words, Web sites that you never tried to reach could send a message looking like a response and it would be stored in the cache. This is a security hole that might allow unauthorized DNS servers to send invalid information for the purpose of misdirecting subsequent DNS queries.
Again a Registry edit is called for. To disable responses from sites that you never asked for, create a DWORD entry named QueryIpMatching. Put it in the same Registry key above and give it a value of 1.

Interesting. Perhaps my IP address theory is just part of another problem.
I Googled the solution for Windows 7 and came across the following: http://www.speedguide.net/articles/windows-2kxp---more-tweaks-158
This conflicts with the link you posted. Which is correct I wonder?
MaxNegativeCacheTtl=0 (DWORD, default value: 0x12C (300 seconds), range: 0x0–0xFFFFFFFF seconds) Description: Determines how long an entry recording a negative answer to a query remains in the DNS cache. When the time specified in the value of this entry expires, the DNS client deletes the answer record from cache. This is a Windows XP and 2003 Server setting only, the Windows 2000 equivalent is NegativeCacheTime.
NegativeCacheTime=0 (DWORD, default value: 0x12C (300 seconds), range: 0x0–0xFFFFFFFF seconds) Description: Determines how long an entry recording a negative answer to a query remains in the DNS cache. When the time specified in the value of this entry expires, the DNS client deletes the answer record from cache. This is a Windows 2000/2008/Vista/Windows 7 setting, for Windows XP/2003 please use MaxNegativeCacheTtl instead.

These questions came up from upstream post. See: http://my.opera.com/community/forums/findpost.pl?id=8797471
Why does reboot correct the n-1 stall problem when cleaning private data (Opera caches) does not work?
A reboot clears the DNS Cache!!
So, why does it sometimes take more than one reboot?
Sometimes the DNS Cache "memorizes" the contents of the DNS caches over a reboot.
What to do?
1) Flush, 2) Reboot,
Or, 3) modify DNS Cache parameters in registry. See post above.IF on a LAN, then you may need to refresh/restart your router.
Finally, if your local ISP DNS servers are sluggish, causes unusual delays, errors, switch to OpenDNS (very fast, free).

* Clean installation; install in separate folder (i.e., Opera 11.01)
* No blocked content; no ad blockers, etc.
* Disable/delete hosts file.
* Delete all Private Data (Tools).
* Restart to Flush DNS Cache. Or, Command Prompt and type: ipconfig /flushdns (press Enter). If LAN, may need to refresh/restart router.
Alternatively, make registry edit:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
MaxCacheTtl (DWORD) Data value: 86400 (default value; 24 hours)* Auto update set to notify when updates available (to be able to install in separate folder)
MaxNegativeCacheTtl (DWORD) Data value: 0 (no reason to store negative responses)
QueryIpMatching (DWORD) Data value: 1 (Create this DWORD entry; disables responses from sites that you never asked for)
See: http://my.opera.com/community/forums/findpost.pl?id=8798191
Optional (may help):
* Enabled plug-ins on demand
* Set memory cache to fixed value: 400MB; empty on exit
* Application cache=yes
* Some user javascripts can cause conflict when Opera upgraded
* If you want to use hosts file(I do!): recommend MVPS hosts files and HostsMan w/HostServer
Hosts file may still need to be modified to remove problem ad urls for some sites.
The n-1 incomplete loads drove me nuts. I stumble upon the above. Works. At least, this has worked for me...now over a week and absolutely no n-1 load stalls.

You just need a DHCP Client running to connect to the ISP and a Hosts file can cause a host of problems (pun intended) by blocking too many sites and getting a blank page.
look at my blog if you want some ideas

Besides clearing the DNA cache in your PC, clear the DNS cache in your router (refresh/restart). Also, your ISP DNS server can retain negative lookups, etc. also; solution: use OpenDNS.
More on DNS cache retention HERE.
I suspect GomJabbar may be experiencing the upsteam stuff, i.e., router or spotty, irregular ISP DNS server. OpenDNS is far superior than local DNS servers, IMHO. Of course, one could install a personal DNS Server on their comuter such as TreeWalk DNS but this is usually not necessary unless one wants to access non-standard domains (i.e., biz, corp, web, etc). I've played with this several times over the years. It has been continuously improved and has nice add-ons. It's free. However, if you just want reliable DNS server, OpenDNS is the way to go.
As far as the n-1 incomplete loading with Opera browser, it seems that hosts file that are large (>135kb) tends to slow things down. The mvps hosts site suggests setting the DNS Client to manual or disable it. That is not possible if on a network; they suggest an alternative: flush the DND cache regularly.
However, IMHO, a better solution for large hosts files for faster browsing, especially if you frequently view the same websites (Win XP):
To increase the size of the DNS cache, open REGEDIT and navigate to:If you don't have a large hosts file that's bogging things down, you will not likely see an improvement but if you do have a large hosts file, this should improve things -- Zoooooooooooooooooooooooom!
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
Create the following DWORD values:
CacheHashTableBucketSize = 1
CacheHashTableSize = 384
MaxCacheEntryTtlLimit = 64000
MaxSOACacheEntryTtlLimit = 301
Exit and restart.

Well, not such a blanket approach may be suitable for many folk. You really don't NEED a hosts file but some folk WANT to use them (for a variety of reasons). The idea behind hosts files, among other things, is to block sites that have been a sources of bad stuff like the fake antivirus crap, drive-by hijacks, etc. Plus, pages load faster w/o the ads (ever wait while an ad loads?).
If you are on an isolated standalone PC you can disable DNS Client; but, not so on some networks with fixed IP addresses (not dynamic addressing), and not so good to depend on your your ISP's DNS servers are crappy (use OpenDNS).
Excellent suggestion on MTU size (ethernet, Windows registry) to improve browsing speed. I have on more than one occasion discovered ISP MTU configured very low resulting is slow browsing. Seems it happens when they do maintenance stuff. I finally abandoned them and went to OpenDNS.
DNS caches are not the central issue here though. DNS caches are really an artifact of Opera (versions 10.xx and 11.xx) not loading pages completely. While hosts files work fine in IE, FF, etc., it is these later versions of Opera than seems to have problems related to content blocker and hosts files. Unfortunately, through trial and error, all this is about finding a way to get things to work, i.e., a workaround.
Better is changing the Windows "service provider" in the registry greatly improves speed more than anything since it affects system wide.
Microsoft has never lowered them over the years.
I think page hanging is more some dumb 3rd party ad server than anything else causing problems with Opera, since most sites won't even allow a "non-standard" browser. a lot of them have never heard of Opera.

Ummm. Actually, it doesn't make a difference if you mask as IE or FF or leave it Opera. It worked in previous version, so why now? Why with versions 10.xx and 11.xx? Version 9.xx screams through the sites without any hesitation (w/hosts file). No, don't think we can put this off on crappy ad servers UNLESS...there is some kind of conspiracy among those wild and crazy ad script writers.
But, but, Opera 9.64 works just fine. Or UNLESS previous versions from Opera 9.xx on back were not so discerning about standards as proclaimed? Naw, something has changed with the latest versions. Even Opera's own content blocker can be part of the n-1 page mess. I've corrected my Opera 11.01. It works fine. However, someone (don't recall the thread) mentioned it seemed to be related to having x number of open sites/tabs. I have 23 open now; no problemo. I have not tested it but perhaps there is a number where loading of multiple sites simultaneously (does it?) may cause rendering problems. Dunno.

yeah I think it comes down to each persons set up and PC O/S.
Some sites block older versions agent string.
you can check what the user agent Opera uses, they have different ones with each version. Change it and refresh the page to see the next ID string.

I've played with this several times over the years. It has been continuously improved and has nice add-ons. It's free. However, if you just want reliable DNS server, OpenDNS is the way to go.
I have been using openDNS for several years. I also have been using the MVPS HOSTS file for awhile. I find the MVPS HOSTS file speeds things up for me.

Sorry, I don't buy that as the cause of the n-1 issue unless Opera is just a house of cards. Has this been tested and found to be a contributing factor or a guess? I understand that some sites don't accept Opera so we have to fake it. But this is not a user agent issue at all. It is not a problem of a site not loading but sites that load, up to n-1 elements (and never time out). Strange as it may be I even Opera forum site n-1 loading at one time -- on two desktops, one laptop! (See sibelius' post above: "I am using FF to post this. I ccould not load the forum in O.") Is Opera so broken so as to have a user agent break it? Geeez. I do not believe that to be an accurate attribution to the n-1 incomplete loadings.
If it all depends on an individual's setup -- and versions 9.xx worked and now versions 10.xx. and 11.xx fail to load -- then is Opera so delicate and unreliable that is a house of cards? I have never had a problem even close to this with IE or FF. No, there's other issues here related to how scripts are read.
As for Opera being standard compliant so much so as not to load these sites is the perfect market share formula for IE, FF, etc. because they work -- with hosts files! Unfortunately, sometimes the standards thing is suggested as an ubiquitous reason, like many tech services telling customers to reinstall or reboot when they have no clue. I recall way back many years ago when all these 'conversations' were on newsgroup and this was discussed ad infinitum. It is one thing to follow standards but the average person doesn't give a flyin' hoot owl's hoot about standards, just what they can access and can see/use - reliably. Or, maybe, just maybe there are folk who are pleased when a site doesn't load completely and say, "Hey, look at this! Opera is strictly compliant! Good news that the loading has stalled and I can't access the Opera forum."
If a person needs to check his bank account records and the Opera browser hangs with n-1 elements loaded, how long would that person be expected to continue using Opera? Without so much as giving a microsecond thought to standards, user agents, etc., that person will go with what works reliably. http://my.opera.com/community/forums/findpost.pl?id=8798751
What worked? What did not work?
I think I fixed it by replacing an old opera\profile\filter.ini with a new urlfilter.ini.I can load the page in the pic in the first post.
Keep fingers crossed.
I still have t see what is the problem in my Opera portable.

I'd really like to know how it works out with Opera portable.
Other info: earlier I commented that I had read (somewhere in these forums) that too many open sites/tabs could cause n-1 incomplete loading of site pages. I did an experiment. I generally have about 15-2- open sites/tabs and have had no obvious difficulty. So, I added 10 additional tabs and added more to Speed Dial (10 total). I then restarted. Sure enough, n-1 errors on 4 sites. Reboot and still a problem. I then deleted those additional sites (18 open sites/tabs; 5 on Speed Dial) and restarted. All worked well. I did the same with FF: added 25 sites/open tabs -- all loaded fast and complete. Added 10 more; still all loaded fast and complete. I can only guess that with the large number of site loading simultaneously that Opera runs into problems if a javascript request is not immediately available. Regardless, keeping open sites/tabs/Speed Dial to a maximum total of 18-20 or less should improve performance.

Regardless, keeping open sites/tabs/Speed Dial to a maximum total of 18-20 or less should improve performance.
UPDATED SUMMARY:

* Clean installation; install in separate folder (i.e., Opera 11.01)
* No blocked content; no ad blockers, etc.
* Disable/delete hosts file.
* Delete all Private Data (Tools).
* Reduce open sites/tabs and Speed Dial to a maximum of 18-20 (the fewer, the better; adjust as necessary).
* Restart to Flush DNS Cache. Or, Command Prompt and type: ipconfig /flushdns (press Enter). If LAN, may need to refresh/restart router.
Alternatively, make registry edit:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters
MaxCacheTtl (DWORD) Data value: 86400 (default value; 24 hours)* Auto update set to notify when updates available (to be able to install in separate folder)
MaxNegativeCacheTtl (DWORD) Data value: 0 (no reason to store negative responses)
QueryIpMatching (DWORD) Data value: 1 (Create this DWORD entry; disables responses from sites that you never asked for)
See: http://my.opera.com/community/forums/findpost.pl?id=8798191
Optional (may help):
* Enabled plug-ins on demand
* Set memory cache to fixed value: 400MB; empty on exit
* Application cache=yes
* Some user javascripts can cause conflict when Opera upgraded
* If you want to use hosts file(I do!): recommend MVPS hosts files and HostsMan w/HostServer
Hosts file may still need to be modified to remove problem ad urls for some sites.

I have 4 sites in quick dial, they do not always appear upadated
I use to have 20+ tabs open, often several Youtube videos loading.
I use auto update. Not for the last version because I read problems, but at some point I will update.
I do not clean install since some time. Too much time to backup, tweak again.
I flushed DND, no result
I edited registry, no result
I cleaned old url filter=good result, till now, I keep fingers crossed.
Some time ago I had to kill coolirisalike.js from my userjs it messed with facebook and frames in some websites. So have a look in your userjs folder if you have a problem.
About Opera portable, I still have to check. I do not think I have a urlfilter there.

No confusion since I understand that you don't use hosts file, content blocker, etc. as commented on previously. You have pretty much a plain vanilla, non-fancy,
clean install (separate folder) setup. BUT for those who like to use hosts files, whether with Opera, IE, FF, etc., this should be THE very first-step. If that doesn't work with a plain vanilla setup, no need to mess with hosts file.What the tabs reveal, if that is the word, is that somehow a squeezed bandwidth (with all those site loading), unlike previous versions (pre-Opera 10), causes n-1 problem. BTW, this is the first time I have been able to duplicate n-1 by choice and corrected it by choice -- an n=1 experiment. So, depending on your internet connection (high-speed broadband, etc.) you might experience differences. Maybe. However, this is not necessarily true since I've been doing some heavy downloads (FF browser) and simultaneously be working with Opera (20+ tabs) -- plus other active machines on the LAN -- with no problem at all. It may just be incidental artifact of Opera's sequential rendering.
In any case, I've been able to solve it on ALL my desktop machines (5 systems on LAN) and 3 laptops.
Of course, never a problem like this with IE or FF. I think we've said this before because I now hear echoes here.
When I get some time I will try setting up hosts file with commonly used sites with addresses to see how things load under varying conditions. I think the resolution order for TCP/IP is local, hosts file, then DNS. This essentially by-passes DNS cache. There are ways to preload the DNS client resolver cache but I'll not mess with that.

Cleaning the urlfilter.ini ian Opera portable worked OK.
Still sometimes any version of Opera takes a bit to load the whole page and few I need to refresh.

No, no, no, wrongo. Not tabs, not hosts file, not BW, etc. These are merely facilitating variables or co-factors but not the core cause.
In any case, a workaround solution has been provided for those with the problem. Enjoy! Glad to see that sibelius finally got things working.

Probably, the reason why the "My Photos" Flash content on

If you go to "Menu > Page > Developer Tools > Reload From Cache", you will see the Adobe Flash content appear. However, this is only temporary because once you minimize the window, the Adobe Flash content is hidden again.
Timing...
Oh, you need timing a tick a tick a tick a
Good timing a tick a tick a tick a tick a
Timing is the thing
-- 1960 oldie by Jimmy Jones
There is no way to predict when n-1 will occur. Random. Reboots somehow cleared it up. Seem like some kind of timing issue (see more comments on this below) that may be site dependent (external scripts).
I suppose we could eventually have a long list of things that we find that appears to be a cause. That's why I really think they are just artifacts or correlated issues that impact the way pages load. The open tab thing also depend on the specific sites you might have open also. DNS, tabs, hosts, BW, etc. are just a few things that illuminate the problem. Somehow, someway, Opera chokes. It is an Opera browser issue.
Thinking aloud as I type on the page...why would Opera have such a problem (n-1) when other browsers loads in a flash, even older Opera versions? It seems to be a timing issue. It is as though Opera "reads" the page and if the external data is not delayed in any way, then it loads. At other times, if anything interferes (could be other apps opening, downloading in progress, or anything that impacts incoming data) such that the reply to a request is delayed, then n-1. I happens ONLY on javascripts. That is why disabling javascript works -- javascripts are skipped. Okay, but if you click on a button or link on a site and get nada, its due to not having javascript enabled.
So, what is this delay about? My guess: On some sites the request for external scripts, etc. may take a long time -- and there does not seem to be a timeout, so Opera waits and waits. Reboot, new request, and a-hah, it works.
All of the things we've discussed here are good tuning tips though they are not the underlying cause; they simple alter the timing window. You may ask why then does my Opera screams after doing those n-1 solution tips mention a few post upstream?
Answer: Luck.
Well, that's a half-hearted attempt at humor. Yet, it is true. In my virtual world I have about 40 or so sites that I visit somewhat regularly during a week. I have managed to modify my hosts file, use the HostsServer (that give a reply to external requests), and increased DNS cache. In effect, I have made compensating timing adjustments so Opera does not choke. Adding new tabs did not necessarily identify a problem -- it is NOT the number of tabs, but the random choice of specific sites. Some sites have all kinds of javascripts, etc. FWIW, I did add a few sites to hosts file to "preload." That works very well for sites that for some reason do not resolve fast.
It's like the parable of seven blind men and the elephant. Each blind man saw a different characteristic of the same elephant. Similarly, all these other things (hosts file, DNS cache, etc.) are just different peripheral artifacts of one thing: on versions 10.xx and 11.xx Opera browser sequential processing of web pages is much different than previous versions and the sole cause of n-1 incomplete loading.
Why on some system and not others? Plain vanilla works. It's when features are added such as content blocker. Other utilities like hosts file, that do not cause a problem with other browsers, seem to not play well with Opera. To say that it is related to the individual PC setup then, if true, Opera IS crippled whereas older Opera versions, IE, and FF just work.
I never really did spend any time looking into it but I wonder about browser.js (auto download by Opera) that provide various correcting scripts. My file shows 2/23/11 date.
I noticed this line:
// Sending an extra onreadystatechange causes some ad scripts to eat memory
I suppose this had to do with Opera freezing for several seconds. In any case, this is where javascript issue are corrected. Hope someone from Opera can do something with this to solve the n-1 incomplete loading.
Bottom Line: this is not a PC setup, DNS, tabs, BW, etc. adjustment issue. It is an Opera browser issue. If you have the n-1 problem and follow the n-1 solutions mentioned above, you just may be lucky and find the right combination to alter the timing in such a way that Opera works. If you have a plain vanilla setup, it should work right out of the box in its own folder. Content blocker can cause problems depending on the entries. Hosts files seem to conflict with content blocker. Hosts file can effect Opera performance but this can be overcome by following the solutions steps. Reboot often, my friends. Relax and enjoy a Dos Equis beer.
That is the extend of my view, strictly a layman's view. I leave it to those with the skills to pursue this. I'm exhausted.
At this point I send out an appeal -- S O S -- to all the javascript experts here who might be able to write a USER JAVASCRIPT to test as a solution.

did anyone think to try under Preferences, Unchecking Show Thumbnails When Hovering Over Tab
this was an old issue where it seemed to improve page rendering because the Tab Thumbnail when Hovering over it is actually a snapshot of the same page you loaded. So maybe this won't have (2) pages trying to complete all the images loaded at the same time?
Maybe an over simplified answer but try it, because I haven't ever noticed page hanging since I unchecked this a long time ago.

Here is the latest "blind men" list of things that may solve the n-1 incomplete loading:
Added: Disable thumbnails hovering over tab (hobbler)
Added: Delete override.ini
Added: Check for updates (browser.js, etc.)

* Clean installation; install in separate folder (i.e., Opera 11.01)
* No blocked content; no ad blockers, etc.
* Disable/delete hosts file.
* Delete all Private Data (Tools).
* Close Opera, delete override.ini (individual site preferences) to eliminate possible corruption; restart restores the file.
* Reduce open sites/tabs and Speed Dial to a maximum of 18-20 (the fewer, the better; adjust as necessary).
* Restart to Flush DNS Cache. Or, Command Prompt and type: ipconfig /flushdns (press Enter). If LAN, may need to refresh/restart router.
Alternatively, make registry edit:

* Tools-Preferences-Tabs. Uncheck Show thumbnails when hovering tabs.
* Check for updates - will automatically (silently) d/l update browser.js, override_downloaded.ini. etc. Restart.
* Set memory cache to fixed value: 400MB; empty on exit
* Application cache=yes
* Some user javascripts can cause conflict when Opera upgraded
* If you want to use hosts file(I do!): recommend MVPS hosts files and HostsMan w/HostServer
Hosts file may still need to be modified to remove problem ad urls for some sites.
