Confirmed on Windows Vista.
Works: 2007092019
Fails: 2007092020
Regression range: http://bonsai.mozilla.org/cvsquery.cgi?module=PhoenixTinderbox&date=explicit&mindate=2007-09-20+18%3A00&maxdate=2007-09-20+21%3A00
seems to be caused by Bug 396099. Looks similar to Bug 436527.

It's hard to block on this without a testcase; in fact, it probably shouldn't have been confirmed without a testcase.

Comment 4

testcase1 from bug description, some kind of reduced.
More reduction seems to reduce repeatability.
STR:
- Move mouse over "Features", menue opens below
- Move mouse over menue: Sometimes menue disapears

If you don't see this, reload (F5 or ctr+F5) one or more times.

[Boris Zbarsky [:bzbarsky]]

So.... I can't seem to reproduce this.  Anything to help that would be lovely.

Comment 6

- move mouse over "Features", menue opens
- move mouse over the menue, sometimes menue disappears. 
  If not, 
- move mouse out and repeat the steps above up to 10x

 If you dont see the bug, reload (F5) and repeat

This certainly reproduces the bug for me.

Comment 8

[j.j.]

http://www.diskeysign.com/ from the duplicate uses the same scripts "mootools.js" and "template.js"

It shows the bug nicely: 
- move mouse over "Interiour Sings", menue opens below
- move mouse (fastly) down beyond "Metal Frame Signs"
  menue disappears

See http://mootools.net/

Is it possible that this is a performance issue? I was unable to reproduce the bug in the posted testcase, but I was able to reproduce it on the posted site (http://www.diskeysign.com/) when my cpu usage was near 99%.
