Dragging page up causes a jump

Some web pages are formatted in such a way by OM5 that I have to do a lot of scrolling to get to the content that I'm interested in. One such website is Linux Today. This means dragging the page up with my finger. It takes longer than it needs to because if I drag my finger up too far and it goes onto the title bar, the page seems to jump back down a little way.

I know about the ability to jump to the top of the page by tapping the title bar, but I'm not tapping it, I'm dragging my finger up the screen. I'll get better at doing this in time, but I'm wondering if this behaviour should be happening in the first place.

The focus is under login boxes and thats why 'jump back down a little way'.

Ok, let me try and put it more clearly. When I touch the screen and drag up, I expect it to move the page up. When my finger reaches the title bar, I expect OM to no longer respond to my finger. I don't expect the title bar, or login boxes, or anything else to register that my finger is on them at the end of a dragging operation.

I've come to expect this not only through using other apps on my phone, but also from years of using other touch-sensitive devices such as my Pocket PC and my Wacom drawing pad. But for some reason, OM5 appears not to follow this standard behaviour. And I wonder why.

You must have a dumb phone with om4 and now via #3 you can jumping up/down with one stop where is the focus /usually where formated text starts but the focus can be changed via js. After page loading the mouse is not up (is on focus) so you jump down and x2 times to be up.

That's exactly how OM5 android behaves on my HTC Hero. I even tried to force the notification pulldown menu to appear without luck.

Could it be a phone issue? Which phone do you have and on which platform?

It's the LG GC900 (Viewty Plus) with LG's S-Class interface running the Java version of OM5.

I've now discovered that the problem also occurs wnen I try and scroll the page down. I'm trying to look further up the page so I drag the page down, my finger hits the icons below the page and the page bounces back up again. It's getting a little ridiculous trying to reach a specific part of the page.

I did some more testing using the java version with jbed but couldn't reproduce it. Is it just dragging that causes this error? What happens if you tap on a link and then drag your finger up to the menu bar? How do other apps behave when you do the same?

I strongly suspect it's a phone or platform specific problem so I suggest you file a bug report.

You're calling it a "menu bar" but it's what I call the "title bar" - the one that shows the page title and, if you tap on it, you go to the top of the current web page. I'm not sure if we're talking about the same thing.

Ok, I've tried doing it more slowly and it's not quite what I previously described. Sorry for that, but I was trying to describe what I thought I was seeing. What's actually happening is that I tap somewhere on the page and, as soon as I start to drag upwards, the page jumps down and then scrolls up as I drag my finger. It happens when the page is still, or when it's already scrolling. So it's not my finger colliding with the title bar that's the cause of it, obviously. And it's not consistent; I can't always reproduce it.

Tapping on a link and dragging my finger does exactly the same thing. It doesn't seem to matter what's under my finger when I start to drag.

I've experimented a bit more and found that there seems to be a zone in the centre of the screen where this behaviour doesn't happen. If I tap above or below this zone, it seems to scroll ok. If it *is* phone-specific then I could live with it by just being more careful.

Yes, I was talking about the title bar.

That's a bit different, yes. Perhaps you have come across another feature I have discovered. Try double tapping on a paragraph partly outside the screen. Does OM scroll the page to focus on it? Don't tap on a link though. ;-)

Nothing happens when I double tap, whether the paragraph is partly off the top or bottom of the screen. And now I've found another, unrelated, problem. I'll start another thread for that, though.
