This bug should be given lowest priority.

I use two monitors. The right one is my main monitor, and we'll call that one M1. The second extends the desktop to the right, and we'll call that one M2.
When FB windows are extended from M1 into M2, and a pop-up menu is invoked on M2 (like the one that says "Customize..." when right-clicking the Mail Toolbar), the menu appears on the right edge of M1.
However, when the window is moved to fit inside M2, pop-up menus (and tooltip windows) appears near the mouse cursor as they are supposed to do. Also, when the window is extended FROM M2 into M1, the menus and tooltips are displayed correctly.
Finally, if TB is closed while the main window is extended across both windows, the next time it is started, it will fit the window into M1 (ie. not save the correct window dimensions).

FireFox has the same behavior.

MSDN has a section for dual-monitor systems:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/monitor_53sj.asp

Reproducible: Always

Steps to Reproduce:
1.Extend the main FB window from the main monitor into the secondary monitor.
2.Invoke a pop-up menu on the secondary monitor or hover the mouse cursor for a moment over an item that has an associated tooltip.

Actual Results:  
The pop-up menu or tooltip appears on the right edge of the primary monitor.

Expected Results:  
The pop-up menu or tooltip should appear near the mouse cursor.

TYPO in my own comment:
First line:
"The right one is my main monitor, and we'll call that one M1"
Should have been
"The LEFT one is my main monitor, and we'll call that one M1"

Already fixed in the latest branch - will be in Thunderbird 1.5.

It is said on Bug 245418 that this should be opened for Mac only. 

The problem is not solved on 1.5.0.4 and OS X 10.4.5 with dual screen.

Again: Problem might be solved on Windows, but still occurs on Mac. Please reopen.

Sorry - One week of festival has made my brain a zombie. Disregard the last message and leave closed. Bug 314279 is where it's at.
