Status: RESOLVED DUPLICATE of bug 314279

(Firefox :: Menus, defect)

Description

[cryptic-moz]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4

When a menu is displayed, it is shown on the wrong screen on Mac OSX.  This is a brand new bug in Firefox 1.5.0.4.  For example if a 2nd monitor is attached to a laptop, and Firefox is running on the second monitor, if I click a bookmark menu the menu will appear on the laptop's screen.  Same with autocomplete menus for forms, or autocomplete menus for urls typed into the url area.  If I move Firefox onto the laptop's screen the menus appear in the right place.

Reproducible: Always

Steps to Reproduce:
1.  Attach 2nd monitor to MacOSX laptop.
2.  Launch Firefox and move window to the monitor's screen
3.  Click a pulldown menu on the firefox window

Actual Results:  
The pulldown is shown on the laptop's screen instead of the 2nd monitor where firefox is running.

Expected Results:  
Pulldown appears on the 2nd monitor.

I've been running Firefox with this exact configuration for quite a long time and have never observed this bug until the Firefox autoupdate which occured today to 1.5.0.4.
