334498 - message filing sub-menus do not display correctly in a dual-monitor system with monitor 2 on top, when a top-level folder has many sub-folders

Status: RESOLVED WORKSFORME

(Thunderbird :: Mail Window Front End, defect)

Description

[Steven Wertheimer]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Thunderbird version 1.5 (20051201)

When I run Mozilla in the secondary monitor of a dual-monitor
system, and attempt to file a message into a sub-folder of a
top-level folder that has many sub-folders, the cascading
sub-folder menu does not appear when I mouse over the top-level
menu.  The little folder icon to the left of the top-level folder
name changes from closed to open, indicating that the mouse-over
was recognized, but no sub-menu appears.

This only happens for top-level folders that have many (>20)
sub-folders.  It is also monitor-position dependant.  When my
secondary monitor is positioned on top of the primary monitor
(this positioning is as positioned by the 'settings' tab of the
Windows-XP 'display properties' dialog, that you get by
right-clicking your desktop), the problem is the worst.  If the
secondary monitor is positioned to the right of the primary
monitor, then menus display, but they do not fill the screen to
the extent that they should.

This only happens when the window that I'm using is displayed
in the secondary monitor.  If I move the window to the primary
monitor, the problem does not occur.

In all cases where I've noticed this, my primary monitor
is 1024x768 and my secondary monitor is 1280x1024.

My symptoms are not the same as those described in bug 314426.


Reproducible: Always

Steps to Reproduce:
1. Create some local folders that have many (+20) sub-folders.
2. Run thunderbird in the secondary monitor of a dual monitor system, where
   the secondary monitor is placed directly above the primary monitor.
3. Attempt to file a message in a local sub-folder.

Actual Results:  
Symptoms described above in problem details.

Expected Results:  
I should have gotten a correct sub-menu.

Attachment: Vista screen shot ~25 folders deep

Previous screen shot was with monitor 2 to the right of 1.  I retested with monitor 2 on top of 1 (didn't know you could do that).  Still WFM.

I believe this is fixed on trunk.  Please reopen bug if you see this problem running a trunk build
