46347 - Scrollbar Thumb jumps up or down when mouse moves over another mozilla window

Status: RESOLVED DUPLICATE of bug 103325

(Core :: XUL, defect, P3)

Description

[Nikhil Bhatla (gone)]

Netscape Build 2000071810 and a self-built Mozilla of 7/18/00:

1) Open two windows in Mozilla.
2) Position the windows so that the front one is to the left of the rear one, 
so you can still see the rear window just to the right of the front one.
3) In the front browser, open a web page that has a vertical scroll bar.
4) With your mouse, grab the scrollbar thumb and move it up/down 
keeping your mouse clicked over the thumb.  The thumb responds 
appropriately.

Here comes the problem:
5)  Now, instead of moving your mouse (mouse-clicked) up/down over the 
thumb, move your mouse (whil still pressing down) out of the current 
window and to the right, directly over the rear window.  You will see that 
the scroll thumb wil jump unexpectedly.

It appears that this bug has something to do with a focus issue 
concerning scroll bars, where mozilla gets focus/curpos confused when 
the mouse moves between windows.

I experience this bug in OS 8.5 and 9.0, in both modern and classic skins.    
I tested on my Win98 box, but did not see it.

I'm still seeing it, on a self-build I did yesterday.  Will check verification 
builds.

Bug 103325 contains a little bit more details about the areas where mouse 
tracking is buggy.
