192042 - Maximized mail window covers taskbar, can't restore when opened via notification icon

Status: RESOLVED DUPLICATE of bug 137661

(Core :: XUL, defect)

Description

[Josh Phillips]

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 a maximized mail window is opened using the new mail notification icon (by
double-clicking the envelope icon), it fills the screen and covers up the
Windows taskbar, even though the taskbar is set to always on top.  Also, the
Restore button is disabled (although the window can be restored to a
non-maximized state by double-clicking its title bar).

Reproducible: Always

Steps to Reproduce:
1. Set the Windows taskbar to always on top, and set autohide off.
2. Open the mail/newsgroups app, maximize the window, then close it.
3. Receive a new mail notification (ie. by sending yourself a message).
4. Double-click the notification icon on the taskbar.
Actual Results:  
The mail/newsgroup app opens.  It's maximized, but fills the entire screen
(covering up the Windows taskbar).  The Restore button in the upper right is
disabled.

Expected Results:  
The mail app should open, maximized -- but not covering the taskbar -- and with
a working Restore button.

I have only tested this using the Modern theme, and only on WinXP.  I believe
this problem has existed since Mozilla 1.0, possibly earlier (my memory fails me).

I just tested it again, this time using the Classic theme.  This time it filled
the entire screen (just as with the Modern theme), though the taskbar remained
on top (so Mozilla's status bar was hidden behind the taskbar).  Clicking on the
mail window caused it to move in front of the taskbar.

The Restore button behaves identically as with the Modern theme.

Apparently the position of the mail window varies when using the Classic theme.
 Twice, it appeared below the taskbar when opening it from the notification
icon, and once it's appeared above.

I'm still seeing this with 1.3 final (Mozilla/5.0 (Windows; U; Windows NT 5.1;
en-US; rv:1.3) Gecko/20030312). In fact, the issue is *worse* than it was.. I
had this happening intermittently in 1.2.1, but previously it was always
correctable by restarting Mozilla. That is NOT working now.

When I maximize the window, it maximizes to the entire screen height, ignoring
the taskbar. This is with the Modern Theme.

Confirming.
