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 definitely understand the tiring, boring thing. With all the things that we've seen that impacts n-1, why not cookies?
I use global setting (instead of individual site preferences) for all sites:
Accept cookies
Delete new cookies when exiting Opera
To keep the ones I want to keep, I first accept all cookies then delete those I do not want and set Delete new cookies.
I should also do a clean install, but it is too much work to save files. Is there automatic tool for this?. I remember I took notes of the files needed to be backuped for configurationa but maybe there is a tool/soft.
Thanks

About clean installation in new folder: No need to save anything. You can install a new version in a NEW folder (e.g., Opera11.01) and it will coexist with the old one w/o any problems. As long as you don't install over the existing installation you should be okay. Then you will have TWO Opera browsers to play with.

I've never used any kind of auto utility; just did it manually. Bookmarks and Wand. That's it. As for other things like cookies, etc. I started fresh. Of course, you can add other files later. Consider renaming the originals instead of overwriting them, just in case.

I resemble that remark!
But, checking for Updates (Help-Check for Updates) does the same thing. Does not always stop/prevent n-1 incomplete loadings. The reboot at the end of the process may be what helps, at least for the current session, since reboots seems to be the most effective albeit short term.

Site pages not loading. This has also been an issue from time to time with several recent Opera versions.
I am running into this problem on several sites, even www.opera.com.
I just encountered this problem myself too. OPERA 11.01 being unable to load www.opera.com - how ironic is that! Some other sites were also failing to completely load.
It appears that the browser Javascript engine has somehow become corrupt and this method to fix it worked for me:
- Go to OPERA: config: /USER PREFS/Browser Javascript and change its value from 2 to 1.
- This forces OPERA to treat its Javascript engine as corrupt and download a new browser.js on restart.
- Restart Opera.

Strange, I did not have a user.js
I did like it says here and now I have one.
Checking for updates manually
Opera downloads the file automatically once a week, but if you want to make absolutely sure you have the latest file you can follow these steps:
Go to the Browser JavaScript setting and change the value to 1.
Click the "Save" button below the setting.
Use Help > Check for updates in Opera's menu bar.
Opera may tell you no new Opera version is available, but it will still check for a new version of the browser.js file.
Let´s see how it works

There is a forum here on user javascripts: http://my.opera.com/community/forums/forum.dml?id=114
You can find more scripts here: http://userscripts.org/
About browser.js. Since I regular check of updates and can see the files update, it is possible that my Opera was cured of the n-1 infection as a result of an update of browser.js a couple of weeks ago. Could be just another blind man's look at the elephant or it may be the solution. Makes sense, since it involves javascript. I don't use autoupdate feature but do it manually. As it checks, it downloads some updated files, if needed. However, setting browser javascript to 1 causes it to download/overwrite regardless.
I see that you've use Opera since v2.12. Wow! If memory serves me, I dabbled with "crash" version 3.62 or something like that. I think I still have it on one of my museum PCs. Back then it was a novelty but faster than Netscape and IE. I used version 6.xx in parallel to IE. I never used Opera as my primary browser until version 9.xx.
Let us know how things go...

Is this the "elephant" whose characteristics "blind men" have described upstream on this thread? Could Turbo impact timing? Sure matches up with some of the things we've seen.
May explain why the n-1 incomplete loading has been associated with versions 10.xx and 11.xx. Turbo was made available on Opera 10. Sure, explains why my Opera 9.62 on another machine hums along.
Open tabs have been described as a possible cause. Increased number of tabs/open sites may have triggered Turbo into action (if set to Auto or if On, contributed to n-1).
Why do reboots work? Maybe (guessing) it clears the turbo decks, so to speak, and Opera loads without Turbo active (If set to Auto) and manages to fill the pages, all n elements. If Turbo is on, then it may just mingle the mix so things load okay (but may take several reboots) At other times, turbo may kick in. Of course, if you have turbo On then the problem would be pronounced. No need to go down the list (all cited upstream) but Turbo sure seems to explain a lot. One way to know for sure if this is THE "elephant" or just another characteristic: if you do no need Turbo, if On, turn Off, if Auto, turn Off.
More on Opera Turbo...
Opera Turbo is "a server-side optimization and compression technology that provides significant improvements in browsing speeds over limited-bandwidth connections by compressing network traffic."
A proxy server accesses web sites through other computers (servers). When you request a web site via your PC the request goes to the proxy server; it is retrieved by the proxy server and then sent back to your PC. The Opera Turbo proxy servers use a compression process to reduce download size, thereby speeding up the web page display.
"Turbo uses a technology called 'Opera Web Optimization Proxy'... Web sites layout and text will look exactly the same, but image resolution may appear considerably lower as a result of the compression. Dynamic Web technologies such as Ajax (XmlHttpRequests) and Flash are supported, but some plugin content will load only after clicking on the empty element."

If you do no need Turbo, if On, turn Off, if Auto, turn Off:
* Turn off Turbo (Tools-Preferences-Webpages, Click Details, Check Off, OK)
As I think back to a couple of weeks ago (when the n-1 partial loading stopped) I do recall changing Opera Turbo from automatic to off. I did not do it as a troubleshooting thing, just something I did reviewing settings. It was a casual thing since I thought 'automatic' really did not have any benefit with my high speed internet service so I turned it off. I suspect that the 'automatic' setting has a threshold trigger point that is tripped when internet speed momentarily slows (multiple sites loading simultaneously, heavy download traffice, or for whatever reasons). Until now I never gave it much thought as it being a possible cause of the n-1 phenomenon. It might explain why n-1 incomplete loading is often random (i.e., unpredictable) and site dependent. It was the randomness of it all that lead me to believe it to be somehow connected with timing or the way pages load in Opera. I have done some experiments on other machines and the results seem to indicate Opera Turbo to be the major factor or certainly a confounder among many for this intermittent, persistent problem. Need more time to validate.
Does turning Opera Turbo OFF solve your n-1/n element incomplete loading problem?

Delayed Script Execution: "Primarily for low bandwidth devices, not well-tested on desktop. Ignore script tags until entire document is parsed and rendered, then execute all scripts in order and re-render." Similar to "Redraw when loaded"? May be the same thing.
Yeah, for low bandwidth. I'm on high-speed internet. But, really, what a joke when one has to resort to this kind of thing to get Opera to load pages completely when...OLD versions of Opera load just fine as does IE and FF.
Okay. Tried it out. It takes a loooooong time for sites to load most sites (10 open) and -- with n-1 errors! This made things worst than ever. You know what's really funny? n-1 with www.opera.com! So much for that.
But it highlights script execution. I still contend that this is some kind of timing issue, probably something with Opera's new javascript engine (Carakan engine was introduced in Opera v10.50) and/or the Presto rendering engine (Opera 10.50 used version 2.5; Opera 11 uses version 2.7). See Opera version history here: http://www.opera.com/docs/history/#down
Solution! Absolutely no n-1 incomplete loads. You heard it here first! Here is a solution that works, guaranteed, without all these "fixes" and multiple restarts: Opera v9.64!! I've gone back to v9.64 on the other desktop in my office but you could try any version prior to version 10.50. Opera 9.64 is an eye-opener. I can have 15-20 open site/tabs and it loads them in a flash. In contrast, even when Opera 11.01 does load all sites, it is slow to do so by comparison. Amazing. Also, lastest versions of IE and FF load fast.
BTW, although I've been able to get most site pages to load I have been running across a few others that exhibit n-1 errors. The only thing I have found to get Opera 11.01 to load sites completely is to restart, sometimes repeated restarts and, when all else fails, reboot. Sometimes reliability matters. When I access a site looking for information and it fails to load completely, I don't waste my time to restart Opera; I start IE or FF because they are reliable and load in a flash. Sad to say but FF is now my primary browser. Opera 11.01 is relegated to tinkering-tweaking experiment.
Yes Opera 9.64 was good
as was v 6 too

I suppose it needs low bandwidth to work. It gums up the works for me. It took five restarts to get most sites to load. Some never did (and they had earlier). The Opera home page finally came around too.
Regardless, I've given up on it. I have just installed Opera 10.10 (first turbo version but before the newer javascript engine) on this machine. If it works well, I will stay with it as backup browser to FF.
I have several friends that I convinced to try Opera some time ago. All high speed internet services. Most have this very same problem. They are in different parts of the USA. However, they don't mess with it and just use FF or IE. I was asked for a solution. Easy; FF or IE. Other friends have absolutely no problems at all or so they say.
I have broadband.
What I am trying now is disabling hardware accelerations in flash and Delayed Script Execution enabled.
I hope nex version of Flash/Opera solve problems.
Reverting to an older version of Opera is an option, please post results.

The problem with n-1 is that it is variable and soetimes resolve with a restart, so if I pass a URL most probably ayou won´t be able to checka it. If you had this problem you will have noticed.

Site to check? Low budget server? Ready? You'll love this one:
www.opera.com

No joke!
As for the Opera site and others, restart once or twice and it loads. It's random. Restart-reboot combo will often lead to a nice loading. It will stay that way for that session only -- reboot and it will likely reintroduce n-1 incomplete loading.
However, let's say that a site has a low budget server and let's say that it has script errors galore. Opera 11.01 can't load the site completely. What then? Go to ye ole trusty Opera 9.64 or 10.10 or even IE or FF -- and page loads in a flash. Bingo! Same machine same setup, etc. BUT, I repeat myself. It's all posted upstream.
Someone told me that this was due to Opera being very strict about following standards. Huh? Reminds me of some companies that proclaimed that they had strict ISO9000 standards and therefore they made quality stuff; turns out they made some of the best quality junk ever known to mankind.
Ultimately it is product performance that is paramount. Naw, I don't buy the standards thing as a cause for n-1 problems at all because they are not site dependent. So, Opera versions 9.64 and 10.10 load super fast. So what's different? One characteristic is that when you disable javascript these sites load!! Even the Opera home site. But, if there are essential javascript links on the site you are up the creek. Note that recent versions -- when the n-1 problem started to manefest itself -- introduced a new superfast javascript engine! What's the common thing here? Let's see...could it be...all together now: J A V A S C R I P T?

I tried your link. You're gonna love this: it loads fine!
Sorry, about that! Don't you love it when you get that reply?! 
But, I got n-1 incomplete loading with Opera 9.64. (Just joking, Opera 9.64 loads it fast!)

Say, I got to wondering if the loading problem (timing) might be due to high-speed internet being a bit too fast for Opera and somehow it just can't handle it or if somehow, even with high-speed internet, Opera's new javascript engine is too fast. All assumes one has a fast PC with plenty of memory, etc. I tried this and found that it did improve things a bit.
Put in address bar and enter: opera:config
1. Go to Extensions
opera:config#Performance|NetworkBufferSize
Set Network Buffer Size to 64 or 128, 256
SAVE
2. Go to Performance
opera:config#Performance|MaxConnectionsServer
and do this:
Max Connections Server: 32
Max Connections Total: 128
UNCHECK these if checked:
No Connection Keepalive
Non-Compliant Server 100 Continue
Reduce Max Persistent HTTP
If you have Synchronous DNS Lookup checked, UNCHECK it also.
Leave everything else DEFAULT values.
SAVE
I tried these setting with 60 open sites/tabs. All loaded clean but because I had so many sites loading it took about 45-60 seconds. NO n-1 but this is not the grand solution I am sure. This is just a tweak and like all the others may not work every time.
I tried it with 20 sites/tabs and really loads fast. I tried it with 5 tabs and got one n-1 (had to restart). Anyway, as I said, this helps but is NOT the solution.
I loaded Opera 9.64 with the same sites. Loaded clean in a flash!
Maybe better browsing when Opera 11.10 final is released.
j
Also although the page is blank, when you'll look at the source code, the whole html code is there.
To recreate the problem I always do the following:
1) You'll need to be blocking some javascripts. I always use the MVPS hosts file.
2) Open multiple tabs on a website which are generating javascript errors because we're blocking the js.
So could someone confirm this:
- Go to http://www.picsearch.com/index.cgi?q=Nuclear%20Reactor&cols=6&width=1400
- Open the Error Console and make sure that there is a "Uncaught exception: ReferenceError: Undefined variable: urchinTracker"
- Open the Panels (F4) and from here open the Links Panel.
- In the Links Panel, right-click on the 3, then hold Shift, go all the way to 15 and right-click on 15
- You'll now have the option of opening pages 3-15 in a background tab. Open those tabs.
- Some tabs now have the n-1/n problem.
All the other browsers (ie, chrome, ff, opera 9.64) have indeed no problems with this.
Another example why this is the Phantom of the Opera: I tried your exercise. I use MVPS hosts and every single link (3-20) in background tabs opened quickly without a single n-1 incomplete loading. So, I closed the tabs and did it again and several did exhibit n-1. Restart and they all load. However, this is at least a way to try to duplicate the problem...sometimes. Numerous open tabs will on occasions exhibit this, but not always, as described thoughout this thread.
Amazingly, as mention above also, I opened 60 various (not multiple pages of same site) site in background tabs and had some sites exhibiting n-1 problems. I load the very same 60 sites in Opera 9.64 and it is amazing how fast ALL sites opened!
I would like to point out that using hosts file is not a factor (although another issue, some sites may not load; remove the entry in hosts file). Javascript doesn't have to be blocked to cause this (see upstream comments); it can and does happen without hosts file. In any case, why should hosts file be a problem with ONLY Opera? There are many things that seem be the cause but are only "blind men" characteristics of an "elephant." As mentioned above, anything that alters the timing or rendering of page loading appear to play a role -- at least for that session. Since this is not a problem with older versions of Opera or other browsers, the n-1 incomplete loading is especially unique to Opera 10.xx and 11.01.
Welcome to the new ultra fast javascript engine, the Phantom of the Opera.

Is this a bug? How would it be reported?
1. Go to Extensions
opera:config#Performance|NetworkBufferSize
Set Network Buffer Size to 64 or 128, 256

2. Go to Performance

and do this:

If you have Synchronous DNS Lookup checked, UNCHECK it also.
This is something I just wrote on my Blog Photo about if anyone came across it.
But I think lowering the Maximum Connections per... is better performance overall because too many connections and then the Newsgroups wont function.
Network Buffer lowered seems better for downloading speed.
Yes turn off that dumb "Pipelining" setting that everyone thinks makes it go faster, it never does unless someone running a server actually can tell you if its on and they accept it.
Synchronous DNS should only be on for Dial up not Broadband, thats an oldie discussed topic.

I used to tweak this kind of stuff with IE and FF in the early days when internet was dialup. You have to see what works for you. Higher connections/server has alway worked well for me. Although you tend to think the connections make a big difference I find that the network buffer seesm to work for me. Never, ever noticed any difference with pipelining although years past it did make a difference in FF.
One could make a case for they type of computer (CPU, RAM, etc.) but I have a variety of machines with the slowest CPU of 2.5GHz and 3Gigs RAM. Others are fast, duel-core, state-of-the-art machines -- all connected to the same LAN.
Either data is getting to Opera too fast and jamming the works or data is getting to Opera too slow. Could very well be both. With multiple tabs open it certainly takes a long time to load -- even when it does not generate n-1 errors -- but Opera 9.64 handles these multiple tabs with ease. Opera 11.01 rendering engine/javascript engine is overwhelmed by the data whereas Opera 9/64 hums along. I have seen it happen on a single site (one tab) direct connected to high-speed internet (router bypasses) also which may be that too much data, too fast overwhelms Opera 11.01. All those lower connections settings, etc. are great for slow connection but for me with high-speed internet nothing is slow coming in so that is why I tried the more aggressive settings. However, I would like to point out that even with me doing heavy downloads on one LAN machine I've noticed no difference in other machines performances, so there's plenty of bandwidth to go around.
I think that there is an optimum data input rate range that Opera 11.01 handles very well but above or below thresholds, not so well. Beyond a doubt, it is Opera 11.01 issue and related to timing, rendering, and javascript. It is also drive-you-crazy intermittant, now you see it, now you don't.
Well, if we get enough "blind men" info we will have painted a good picture of the "elephant" aka The Phantom of the Opera. If anyone finds these Performance connection and buffer settings help, please post and let us know.
The question I have is how do report this -- as a bug.

Thanks for looking at the photo.
How about this test, I think you mentioned you have Opera 9.64? I wonder if it would render faster in that?
Should have mentioned this before but,
My State's Lotto website decided last month to "update the pages" instead of the old plain just the numbers listed for quick checking of tickets.
They went overboard!
Now it has color, flash animations, numbers listed all over making it harder to find things, images of scratch tickets...
Well instead of a quick fast page load like before, it now can take a minute or more just to load the home page!
It can get frustrating with n-1 hang!!! somethings just won't load.
Let me know what happens.

Well, I am of no help. The site opened and loaded pretty quickly. I restarted (thinking I might get n-1 to kick in) and it loaded nicely with no n-1 incomplete loading (see image below). I had about 10 open tabs. I also open the links on the toolbar and they loaded okay. All opened in about 10 seconds.
I loaded it in Opera 9.64 and it loaded in about 6-8 second -- it went through the address bar elements fast. I had 6 open tabs in Opera 9.64. Firefox 3.6.13 (with 5 open tabs) opened the site in about the same time as Opera 9.64. Surprisingly, IE8 loaded the site in about 2 seconds (but only one other tab open)!

opera:config Cache , ECMA Script, it has a number 2000 which could be reserved memory (kb?) used for Javascript rendering?
Is this some average setting used globally ?
Since most web sites now have Javascript overload, could this be increased to help page loading and stop n-1???

Opera slowed to a crawl.

I Didn't like that pages not wanting to load.(n-1) so I lowered them down like I had it before, now its Ok again.
Other than slowing it to a crawl did you get n-1?
Now that you readjusted, did it correct n-1?
Maybe much lower settings will work best for your setup. Always reboot after changing settings.

Consider tweaking the system. Here's something of interest. This is an old tweak I use on my Win XP.
Control Panel-Admin Tools-Component Services, Event Viewer, System. Look at Event column for 4226. Even so, you might want to consider the tweak -- change 10 half-open connections to 50 or 100 -- or set the limit back to 65,535, the original default. Note: this often goes back to default with certain Windows updates. Windows 7 does not have this limitation but has the original default of 65,535 -- so I understand.
See:
1. http://blog.davidkaspar.com/archives/2005/04/windows-xp-sp2-and-event-id-4226.php
2. http://lvllord.de/?lang=en&url=toolsYou can find out which process is responsible for the many half-open connections with the command 'netstat -no | find "SYN"'. Half-open connections will have a state of other than ESTABLISHED. Note the PID (process id), open Task Manager and locate the process and application responsible for the half-open connections.
The second case means that SP2 is stalling your work. An unofficial patch will modify the locked tcpip.sys and let you set the limit to whatever you wish. 50 half-open connections is a reasonable limit or you can set the limit back to 65,535 which it was before the SP2. The patch is called EventID 4226 Patcher and can be found on LVL Lord's web site.
Also, see:
http://half-open.com/
Note: THIS will not affect download or internet speeds per se. It fixes a problem when reaching limit of 10 half open TCP connections. A half-open connection differs from a fully-open connection. With TCP 3-way handshake, a half open connection is one where the initial (SYN) packet has been sent by your computer (to request a connection) but not acknowledged (SYN ACK packet) by the server. Note that ONLY XP suffers from this AFAIK. Great if you use proxies, torrents, and P2P apps.

Should I apply the patch? And how to revert to default? I just run the patch again?
browser.js is enabled
Thanks

Disable AVG for this patch. This is not a virus. I used to use AVG but abandoned it for Microsoft Security Essentials. Easy. Simple. Reliable. The latest version upgrade was a great improvement. It's FREE. http://www.microsoft.com/security_essentials/support.aspx?mkt=en-us
Run and follow these steps:
Do you really want to change the limit to 10? C (you do not have to press Enter!)
Please enter the number of concurrent half-open connections: 100 (press Enter)
Do you really want to change the limit to 100? Y
May these files be renamed until end of patching? Y
The patch will then do its thing.
You will see Windows File Protection popup asking if you want to change the file or revert to original or something like that.
Select Cancel
Then WFP asks,
Are you sure you want to keep these unrecognized file versions?
Yes
Press any key to exit. Reboot!
Tada! Done!
If you are not sure if it made the changes run it again. You will see the number. If okay just exit.
Save the Event ID 4226 Patcher for future use.
I used to get those 4226 events a lot. This patch stopped them. I don't know if this makes any difference as far as n-1 incomplete loading of web pages but it is a nice tweak that may make browsing better overall -- in any browser.
I used http://half-open.com/download_en.htm to set 100 which is quite simple and AVG did not blocked.
I don´t like any antivirus very much but thanks for suggesting Microsoft Security Essentials. I would have to uninstall AVG. In my experience two AV do not get well.
I can´t favorite this thread. I want to keep it visible if I have to undo the any modifications I made.

This really helped speed up page loading (but may not help with n-1). You may have to find value that works best.

I never knew FAST complete page-loading w/o restarts could be so wonderful!
Anyone try Opera 11.10 beta? Any improvement?
Tried the Minimum and Maximum on both settings for Maximum connections to Server and Maximum Total.
From 1 to 128, it gets strange results.
Lower settings seem best for text pages, but with lots of flash or photos higher seems to work.
Its like 50/50 with the n-1 page hang, waiting for connection #1 or sometimes #2, weird.
I lowered Max connections per Server/Total in Firefox to (8/20) and that responds faster and no hanging elements.
Maybe it is the Javascript and it has a mathmatical error in its code somewhere?
That State Lotto web site still takes too long and hangs elements, annoying.

After re-reading that older thread it kinda "hit me"
That maybe there is no such thing as n-1 hang at all.
People see it because they have the "Full" Progress bar showing and that Progress Bar itself is the problem.
Someone mentioned that it might be just the Progress bar problem and watching it, not an actual problem in loading the page.
When I put the Progress Bar on the "Simple Version" the pages loaded fine, I could still see elements loading but never got stuck on the last one.
It completed. (or turning off the Progress Bar altogether)
So whoever designed the Progress Bar, Full pop up on bottom or in the Address Bar, made some "quirk" mistake in its design causing it too get stuck? (My thoughts)
The simple Progress bar version just seems to do the job right.
Maybe thats all it is.
Not the DNS Cache or Ethernet, TCP/IP stack, Network connections, etc...
BTW I have lowered my network connections in Opera v10.62 to 2 per Server and 4 Total (like the old days)
It seems even better response time in the Opera Forums right here.

My experience has been that part of the page is missing on most of the n-1 errors. It is not that the n-1 in the progress bar is false -- I get loading activity (mouse cursor hourglass). I use the simple progress bar. It is hung waiting for something, it seems. Sometimes I get only the header. Only when one can get it to finally oad (restarts) will the pages load completely. On some sites, no errors on the error console; others no javascript errors but disabling javascript somehow allows the page to load completely (but if you need javascript on the site, you are outta luck); others CSS warnings, etc. And, in every single case, IE and FF hums. Even my ole trusty Opera 9.64.
What that thread tells me, even though a lot of it was about DNS issues and issues with proxy stuff, is that the thread touches on many of these same characteristics we have seen here. All manifestations of the same core problem,,,ALL pointing to something inherently wrong with the way Opera is handling site rendering or related.

I am not seeing many n-1 hangs even with the Simple Progress Bar, so it could be just some really bad websites with lots of errors, you could always Validate a page just to see if it has errors too.
Opera Menu, Settings, Preferences, Network
What I did was lower the maximum connections per server and maximum connections total
it actually seems to improve page loading
Max connections Server = 2
Max connections Total = 4
try it and see if it flows better.
also, just thinking, do you have "Enable Fraud Protection" ON in Opera?
if you do make sure the anti-virus or spyware isn't running a real time protection service at the same time. You have to use one or the other not both.

I did manage to get Opera 11.01 optimized/tweaked a level where I don't get n-1 often. For a long time now (~3 weeks) I seldom see n-1s, they have been rare. Yet, when they do occur, I try things to get the site to load. I was successful only once and did nothing more than clear the cache and then refresh the page. Sometimes when I go to a new site n-1 bites again. The only "tweak" I have found is reboot. If that doesn't work reboot again, and again. Then it loads and you can proceed with your normal browsing for that session.
Now, that being said, I tried various progress bar setting with Opera 11.01 with ~50 open tabs. I found no difference among the settings that made any difference as far as n-1 incompletely page loadings. However, if you keep on rebooting you can find the sweet spot for that session and they all load. IN NO INSTANCE was the n-1 display merely an incorrect display; there was incomplete loading of the page contents. I have yet to have a complete page display while seeing element not loaded in the progress bar. IMHO, to dismiss the progress bar showing n-1 as incorrect does not correlate with the actual page partial loading.
Ignoring the progress bar n-1 element indication is akin to closing one's eyes so no to see what's in the room. Turning the progress bar off is like turning the lights off at night as a solution to removing furniture in the room.
It's not just the progress bar; this is true for most of the false positive solutions on this thread. It should be noted that a combination of these "solutions" and "tweaks" may actually help (e.g., keep open tabs <10). I think that is why I've able to go without n-1 for such a long time. Why would I abandon Opera 11.01 when it works for me? After using it I still run across n-1 problems, even though rare, it still presents a problem for me when doing business work. I just don't have time to fiddle with it. So, I am in a holding pattern with Opera 9.64 until the next final version. I'm hoping that the fleeting, on again, off again, will-o'-wisp can be captured.

Ahhh, but you just never commited a fraudulent act. If you ever do though, it will alert US!
Now that you brought it up, I've never had it do anything either. I heard it keeps elephants out of tree also. No elephants in my trees so it must be working, huh?
Seriously though, I just don't venture too much outside of my regular online haunts so not likely I would run across such a site. Host file also provides similar protection. Is there a test available for the feature, maybe something like the antivirus EICAR test file?Opera’s Fraud and Malware Protection
http://www.opera.com/browser/tutorials/security/fraud/
http://www.opera.com/browser/tutorials/security/fraud/950/
"Opera’s Fraud and Malware Protection warns you about suspicious webpages and is enabled by default. It checks the page you request against several databases of known phishing and malware websites, called a blacklists. Although it is not possible to totally eliminate the risk of encountering an unidentified phishing or malware website, the risk is minimized."

It's been around since Opera 9.1. Browsers such as Internet Explorer, Firefox and Opera all have "fraud" protection and "phishing" filters either built-in or added on for added protection. I have never run across any recommendation to disable it due to conflict with antivirus (although I've heard that Norton conflicts with everything and leaves residue). Then again, for some, maybe antivirus software scanning causes n-1?
"By default, Opera Fraud and Malware Protection is enabled. With Opera Fraud and Malware Protection enabled, he domain name of websites you visit is sent to Opera’s Fraud and Malware Protection server together with a hash of the domain name which checks it against phishing blacklists compiled by Netcraft and PhishTank, and malware blacklists compiled by TRUSTe. HTTPS sites are checked via an encrypted channel, while IP addresses on the local intranet will never be checked."
It may be that disabling fraud protection changes the timing mix of things so that sites do load better, like some of the other tweaks mentioned in this thread. A genuine solution would be 100% for everyone. I don't think this is the cause and disabling fraud protection the solution.

Opera seems Ok with the way I have it set up now.
Siblius have you looked at my photos on My Opera blog at the settings I have in Opera?
Are they similar?
Are you running WindowsXP with all updates and unneeded Services shut off? How much RAM?
If there are too many running processes in Windows that could take some performance away.
Have you ever checked your Ethernet Card settings that could cause a conflict/slowdown?

Well, well, well. Who would have guessed that their "super fast javascript engine" screams? n-1 incomplete loadings? Not in their lexicon. Added many, many, many open tabs and I could not get it to produce n-1.
