(SeaMonkey :: General, defect)

Description

[Bjorn Stadil]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2a) Gecko/20020910
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2a) Gecko/20020910

This site causes Mozilla to first hang then freeze the computer after 5  to 10
seconds.  The problem occurs when I use the scroll function and scroll up after
having scrolled down more than hald the page.  It happens under Win2000 server
using dual cpu's.  The problem does not occur in WinXP.  The error is
reproducable.   It happens on other sites but this one will reproduce the freeze
all the time.  I can not get any more information as the computer locks up and
has to be rebooted.  No BSOD just locks.  The mouse works for a while and then
freezes as well. 

Reproducible: Always

Steps to Reproduce:
1.  Go to site   
2.  Scroll down more than 50%  
3.  Scroll back up using "slide" function

Actual Results:  
Mozilla stops working.  ALL other Apps not responding.  After 10 sec mouse
freezes and machine needs to be rebooted.  Not BSOD but a Freeze.   Only in
Win2000 server on my Dual CPU machine  (ABIT BP6 dual Celerons  550Mhz)   WinXP
works fine on same machine same version of Mozilla.   All versions from 1.1 
thru 1.2a.

This has been happening on my computer since installing 1.1. It wasnt until
yesterday that I realized it was Mozilla. Using Windows 2000 I can recreate the
exact problem reported on numerous websites. as it happens I will post the URL's
here.

As described, it is just a hard lock, preceeded by a system beep. The mouse
moves around for a while, then the beep, mouse and computer freeze, forcing me
to hard reset it.

Here is the page it was doing it to me on today:

http://www.accessmicro.com/btosystem/

Scrolling down to the bottom of the page, I notice the rendering of the Intel
graphics become distorted, computer stops reacting, mouse still moves, then
beep/freeze.

System:

Intel Celeron 900
Asus TUSL2-C
ATI Radeon 7500
512mb crucial PC 133 memory
