Status: RESOLVED DUPLICATE of bug 141599

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Wolfgang Hübner]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1) Gecko/20021130
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1) Gecko/20021130

When you move Mozilla to the 2nd Monitor in DualHead XP-Setups, the mouse hover
effects vanish as soon as you stop moving the mouse. Try "www.tagesschau.de" and
hover over the roll-out menus on the left to see what I mean. They close as soon
as you stop moving the mouse on the 2nd Monitor. This also happens with all
"OnMouseOver" Messages as well as the "Back/Forward/Reload..." Button in the
Toolbar of Mozilla.

I've experienced this with a Matrox G400 Dual Head as well as with a NVidia
GeForce4 Ti 4200 TwinView.

Reproducible: Always

Steps to Reproduce:
1. Go to any website with "OnMouseOver" Effects (i.E. www.tagesschau.de)
2. Hover over the roll-out menus on the left (i.E. "Fernsehen")
3. Stop moving the mouse while still remaining on this button. The selection 
suddenly vanishes and the menu rolls back.

Or:
Just hover over the "Back" button when Mozilla is on the 2nd Monitor. You'll see ;)
Actual Results:  
Well, I had to move the mouse to activate the menu again.

Expected Results:  
The selected item should have stayed selected like it does when Mozilla is
displayed on the primary monitor.
