222817 - Mouse Hover events doesn't work if application is placed on a secondary monitor.

Status: VERIFIED DUPLICATE of bug 135079

(Thunderbird :: Mail Window Front End, defect)

Description

[Brian Schmidt]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322)
Build Identifier: Thunderbird 0.3 (20031013)

This is a bug that exists in every single version I have tested from Mozilla, 
Thunderbird and Firebird.

When the application (or part of the application) is places in the negative 
coordinates of the screen area (only occuring with multiple monitors), the 
elements that contain some sort of hover-element, that is in the negative area 
of the screen, will not keep the hover effect activated, only as long as the 
mouse moves.

This affects everything, links, buttons, menus, statusbar.

This is a huge annoyance.

Reproducible: Always

Steps to Reproduce:
1. Install any of the Mozilla applications (Mozilla, Thunderbird, Firebird) as 
you would normally.
2. Set up multiple monitor, where you make sure that you virtually place the 
secondary monitor either to the left, or on top, of the primary monitor (or 
anywhere in between, top-left if you like) (Note: you don't have to physically 
place the monitor at those positions, merely in the setup of the multiple 
monitors in Windows).
3. Move the application (Mozilla, Thunderbird, Firebird) to the secondary 
monitor and place your mouse on top of any button that should lift up to show 
that you are hovering the mouse above it. Can try to just move the application 
partly onto the secondary, and you will see that the parts that still remain on 
the primary monitor area works as intended, but the parts on the secondary 
doesn't.
Actual Results:  
The elements that contain a hover effect (buttons, links, menus etc.) only 
flickers while the cursor actually moves on top of it, when the mouse comes to 
a halt the element will act as if the mouse isn't even hovering above it.

Expected Results:  
The application should have kept the hover effect active, rather than only 
flickering it.

I think all these bugs are the same: bug 135079, bug 141599, bug 154163, bug
159277, bug 222817.  I'm putting this in all the bugs in the hopes one of the 5
different owners of these 5 different bugs will fix it and resolve the rest as
dupes; I don't know if I have permission to resolve/dupe myself and I don't know
which one is most likely to get attention first :)

This is a mozilla suite bug, not thunderbird specific, duping.

Please reopen if you disagree.
