30325 - Scrollbar scrolls on mouse move (not drag)

Status: VERIFIED WORKSFORME

(Core :: XUL, defect, P3)

Description

[Akkana Peck]

On my linux debug builds, for the past week or two, I see this frequently in the
browser window, especially in bugzilla pages:
I grab the scrollbar thumb, drag it down a bit to scroll the page down, release
the button, move the mouse left over the content area -- and the scrollbar and
page jump back upward, not to where I started the scroll but partway.

I've tried making sure the mouse pointer is still over the thumb when I release,
then waiting several seconds before moving back into the page; this seems to
help reduce the frequency of the problem but doesn't entirely stop it.

I also see this fairly often if I leave and reenter the window, or if I move the
mouse over the scrollbar area then back into the window content (in both of
these cases, there's no button press at all).

This is driving me crazy -- it makes it difficult to do much with bugzilla
because the page keeps scrolling away from the form elements I want to change,
and I sometimes have to repeat the scroll two or three times before it will stay
in the place I scrolled to.

Mass-moving all M16 non-feature bugs to M17, which we still consider to be 
part of beta2

Adding keyword in the hope that this doesn't get forgotten.  Mozilla is really
hard to use with this bug -- basically, you can't ever scroll by dragging the
scrollbar thumb; you have to click in the trough or on the arrows instead) and
if you forget and drag the thumb, it's very frustrating and hard to get back to
where you were before.

Putting on dogfood+ radar.

I'm not seeing this in a linux build from today. Is this still affecting 
you akkana? (I'm using rh6.1 gnome +enlightenment).

Sorry, I'm not sure -- it was something I saw all the time when I was using the
browser as dogfood, but in the feature frenzy it has regressed to where I can't
use it for real work any more.

dogfood trumps nebeta2, so how this can be dogfood+ and nsbeta2- is a mystery to 
me. clearing nsbeta2-
