Description

+++ This bug was initially created as a clone of Bug #203995 +++

User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4b) Gecko/20030430
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.4b) Gecko/20030430

My build ID is 2003043008. I am using the latest version of Mozilla as of the
30th of April. I noticed this at http://www.whatisthematrix.com. I was in
fullscreen mode. I clicked on a popup window to look at a trailer. The window
was not fullscreened, it was just a floating small window. While it loaded I
tried to access the page behind it (whatisthematrix.com) via the task bar with
the mouse and I could not access it. I then launched a new window, which was
maximized yet not fullscreened and tried to access the taskbar with the mouse.
Still no result, there was no response when I moved my mouse to the bottom at
all. Therefor I believe when any window is fullscreened, as long as it is open,
restricts the ability to access the taskbar with the mouse when in another
Mozilla window (including mail etc).

Reproducible: Always

Steps to Reproduce:

1. Open any URL in Mozilla
2. Hit F11 to fullscreen the window
3. Hit Control-N to make a new window
4. Try and access the taskbar with the mouse

Actual Results:
The taskbar will not pop up.

Expected Results:
The task bar should have popped up because a window that is not fullscreen is in
the forefront.
