180417 - INCREDIBLY slow when swithcing between Mozilla browser windows

Status: RESOLVED WORKSFORME

(SeaMonkey :: General, defect)

Description

[Mike Dodge]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2b) Gecko/20021016
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2b) Gecko/20021016

When more than one Mozilla window is open, switching between the two by clicking
on the taskbar buttons is EXTREMELY  slow, and sometimes does not switch at all.
I can Alt+Tab to switch windows, and that seems to work a little better, but it
is annoying when I'm primarily using the mouse. It takes upwards of 2 seconds,
when other windows on the system (other programs, windows explorer, etc.) come
up in less than one second. Sometimes the task buttons also disappear completely
when a window is switched. Also, it ONLY happens when switching between Mozilla
windows. If switching from a system window or another program to mozilla, the
window appears without a problem.

Reproducible: Always

Steps to Reproduce:
1.Open a browser window to any website (my homepage is www.xp-erience.org)
2.Open another browser window to another URL (this way you can tell the
difference between windows)
3.Try switching back to the first window by clicking on it's button in the
taskbar at the bottom of the screen.
Actual Results:  
The switching is VERY slow, and at times the window does not come to the top at all.

Expected Results:  
The browser should switch to the new window quickly.

Computer configuration: WinXP Home, 1.0 GHz Athlon, 384 MB RAM, 20GB HDD and
second 30GB drive, ZIP, CD-RW, NVidia GeForce 2MX with latest drivers. WindowsXP
is using several different themes when this happens, and the browser is using
the any theme.

Similar, but not exactly the same as bug #136230.

I have found that the problem is actually isolated to when I use the NVidia
40.72 Graphics Drivers for my GeForce card. I do not have the problem with the
previous build of their driver set. I have emailed them with an indication of
the problem, but I don't know which team it will be to resolve the issue. So I'm
informing both groups.

Mike, are you still experiencing this problem with a new build of Mozilla and
the latest nVidia drivers?

I am now using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1)
Gecko/20021130, and have actually updated my NVidia drivers to a beta version
that is not WHQL Certified at present, 42.01 (41.09 is the latest whql driver
available.) This configuration seems to work fine. Through a posting in a
newsgroup similar to the one here
(http://www.techwarelabs.com/community/viewtopic.php?t=2623) I got the idea to
try another version of the driver, and this has solved the problem. I think that
particular version of the driver had problems.
