Scrolling with the mousewheel or by dragging the scrollbar through a long
unordered list brings the system to a halt.  No bluescreen, no talkback.  The
cursor responds but nothing else does, and if I click a few times a get a single
'beep' from the PC speaker and everything freezes.  CTL-ALT-DEL does nothing,
the only solution is a hard reset.

Scrolling with PgUp/PgDn or spacebar or by clickingthe space above or below the
scrollbar (whatever you call that) does not reproduce the bug.  Playing with the
mousewheel settings in mozilla had no effect.

Reproducible: Always

Steps to Reproduce:
1. Load a page with an unordered list (see URL for an example I made up)
2. Scroll with mousewheel or drag scrollbar.
3. hit reset button :-(

Actual Results:  
System freezes.  I get a few artifacts in the text being scrolled, like half a
line of text repeated twice.

Expected Results:  
Scroll normally.

System: Windows 2000 Professional build 2195, SMP (dual Athlon MPs), 512MB
ECC/reg RAM, ATI Radeon 8500 128MB, MS Trackball Explorer, all with latest drivers.

Bug has been independently reproduced by  We are both using the
ATI Radeon 8500 graphics cards on AMD Athlon/Windows 2000 platforms.  I'm told
it maybe be an issue with ATI's newest drivers (v6118).

Further testing has shown that list-style-types circle and disc are the only
styles that cause the crashes.  All others (including squares) work fine.

Last one:  It's confirmed, the issue is with ATI's video drivers version  Reverting back to version solves all the problems
given here.

Hopefully this is being added to the relnotes.
