Status: RESOLVED WORKSFORME

(Core :: Web Painting, defect)

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050420

When smooth scrolling is on, scrolling does not always stop when the mouse
button is released after pressing and holding (shortly) on either the Up or Down
arrow on the scroll bar.

Reproducible: Always

Steps to Reproduce:
1. Go to the given web page ( http://www.komw.net/partyline/thisweek/ )
2. Click and hold on the down arrow on the scroll bar for a short period of time.
3. Release the mouse button and observe.

Actual Results:  
The page continues scrolling.  The scrolling will often continue for a full page
of the display (on a window of about 800x600 pixels).

Expected Results:  
The scrolling should have stopped when I released the mouse button.  I wouldn't
expect the page to continue scrolling for more than one or two lines.

Happens with all themes here -- Pinball, Classic, and Modern.

worksforme with linux trunk 2005060905 and 1.7.8

can you try a more recent trunk build?

I can't reproduce either.

Have you tried at the site given?

In 1.7.10, it still keeps scrolling on its own.  It seems to be more likely to
do this with multiple columns/frames?  (It didn't do it for me, either, on this
Bugzilla page, though it does it fairly consistently on the KOMW page noted.)

sandreas: 1.7.whatever is NOT a trunk build. It's old stuff.

Oops, sorry.
...
Hmmm, looks very different from 1.7.x.  Trying to install a 1.7.x chrome on it
(Pinball 2004-09-15_1.7 in my case, oops) causes a segmentation fault; I think
that an error message would be better. :)

As to this problem, though...
The build retrieved today from
http://ftp.mozilla.org/pub/mozilla.org/mozilla/nightly/latest-trunk/
does correct the problem. While it does not immediately stop when releasing the
mouse button, neither is it continuing for several (like 8) seconds, like 1.7.10
does.

Since it only continues maybe 1 to 3 lines now, I suppose it's acceptable.  The
scrolling is also jerkier (less smooth) than 1.7.10 appeared to be, though.

Sandreas, how is it now with http://ftp.mozilla.org/pub/mozilla.org/mozilla/nightly/latest-trunk/

closable as WFM?

Looks like KOMW's page changed, and it no longer causes this problem under 1.7.x, so there seems to be no point in checking this any more.  (Then again, X has been upgraded in the interrim as well, so maybe that did it...)
