240806 - URL dropdown and popup windows appear only on the primary screen of a dual monitor display

Status: VERIFIED DUPLICATE of bug 135079

(Firefox :: General, defect)

Description

[Dave Bissett]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

I set up a dual monitor configuration on my inspiron 8600 laptop, and dragged
the firefox windows to the external screen.  However, when I click on the url
dropdown, it drops down on the right edge (the external monitor is to the right)
of the built in screen.  Also, clicking on something that opens a popup (an ad
at dilbert.com in this case) opens the add in the right location, but on the
wrong screen.

I just tested the menu bar (file/edit/view) and it also drops down on the
incorrect screen, against the right edge.

I do not have the task bar extending onto the external monitor, so it may be a
function of the laptop not reporting the screen size in pixels correctly.  Other
applications (i.e. msn messenger, and ones that I have written) display the
menus in the correct location.

The above happened after I added the monitor, but before a reboot.  I tried
rebooting, and it worked normally after that.
