User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20050825 SeaMonkey/1.0a
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20050825 SeaMonkey/1.0a

After trying Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1)
Gecko/20050825 SeaMonkey/1.0a the menus in vBulletin 3.0.x no longer work. When
visiting the example above, you should be able to switch the display mode. It
worked with the 20050814 nightly and it works with Firefox 1.0.6.

The strange thing is, that the new vBulletin 3.5 RCs work without a problem.

Reproducible: Always

Steps to Reproduce:
1. Go to a thread in a vBulletin3.0.x Forum
2. Try to switch the display mode

Actual Results:  
Seamonkey doesn't recognize the menu, like it's only visible to the user but not
at the top of the click hierarchy (if one could call it so ;-))

Expected Results:  
Make the different menu points usable like before.

The latest firefox nightly Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US;
rv:1.9a1) Gecko/20050825 Firefox/1.6a1 fails too.

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b4) Gecko/20050825
Firefox/1.0+ is working as expected, so it's probably a error in Gecko after the
branching of 1.8.

Don't see a dupe of this. Confirming. This still occurs with bfcache off.

Confirming for this build. I am a mod for a forum running vBulletin Version 3.0.7
and the drop down menus no longer work. You can drop a menu down, but you cannot
select anything.

Clipping is broken.
The background-color of the link should become green when hovered over. 
It only happens when hovering over the last 10 pixels of the left of the link.
That's no coincidence, I think. See the css code:
left: 390px; clip: rect(auto, 400px, 80px, auto);

So, looking at the regression range again, I think this is a regression from
fixing bug 296036.

My fault; I should have been more careful.  I misread ComputeClipRect.

I just want to say that I experience the same problem with todays Firefox (OS X)
and Camino trunk builds.
The JavaScript menus at https://www.skandiabanken.no dont work properly, but
after applying the above patch it works again! As posted in bug 306218

Confirming both UAs now work as expected.
