640955 - Drop Down Menus Disappear if Browser Sits Idle

Status: RESOLVED DUPLICATE of bug 638386

(Firefox :: Menus, defect)

Description

[0.zer0]

User-Agent:       Mozilla/5.0 (X11; Linux i686; rv:2.0) Gecko/20100101 Firefox/4.0
Build Identifier: Mozilla/5.0 (X11; Linux i686; rv:2.0) Gecko/20100101 Firefox/4.0

When ever I leave Firefox open and sitting idle for ~15 minutes or more and I come back to use it, the drop down menus will disappear when the pointer touches them. This happens to ALL drop down menus:"File, Edit, View...", right-click menus, and autoform selections(logins). The drop down menu will appear but will quickly disappear when the pointer touches it. So far, the only "fix" is to restart the browser and KEEP BUSY!!! ;)

Reproducible: Always

Steps to Reproduce:
1.Open Firefox
2.Let sit idle for 15+ minutes
3.Initiate a drop down menu
4.Try to select an option from menu

Actual Results:  
WHen trying to select an option from the menu, it immediately disappears when the pointer touches it and no selection is possible, no matter how fast you might try.

Expected Results:  
After getting a drop down menu, it should be possible to move the pointer from one option to another, menu staying open as long as pointer is in contact or until an option is selected.

I am using the FF4RC1 from Mar,09(?), i686 from a .tar.bz2

Probably the same issue as bug 638386.
