94717 - onmouseover event when moving mouse over side bar causes browser crash

Status: VERIFIED FIXED

(Core :: CSS Parsing and Computation, defect)

Description

[Igor]

1. Open the URL http://www.nortel.com
2. Move the mouse slowly over the sidebar with the options (Web Store, Customer
Support, Partners, etc.)

Error- The browser dies.

Expected behavior-
The browser should pop up sub-menus

Regression-
The two events in the page source are javascript onMouseOver and onMouseOut
events.  Perhaps this is related to 91431 though but this does not necessarily
relate to changing the element.style.display.

Not likely to be JavaScript Engine. Reassigning to Browser-General
until we can get a stack trace. I have not been able to reproduce the 
crash as described above using WinNT and Linux builds 20010807.  

Igor, which build ID were you using? Please include this in any report - thx.

For the record, I can't reproduce this any more with 2001081303.

Comment 6

[Igor]

Same for me, this bug seems to have mysteriously fixed itself.  The menus now
pop up OnMouseOver without crashing.  I suggest it be resolved as fixed.
