New insight for me, after turning on Nvidia nNview, mozilla menus no longer jump
to the first screen.

Window
 nView Options
  Enable window spanning across monitors
  Enable child window spanning across windows
 Enable application position memory
 Enable dialog repositioning
 Extend application system menus with nView options

Hope this helps.

This is a dupe of bug 21942. See comment #22 in bug 21942 to reproduce this.

[Andreas Kunz]

Sam, Nathan, can you reproduce this with a current trunk build?
Bug 21942 has been resolved as fixed, but seems not really to be fixed. Maybe it
should be reopened, so your info might be helpful.

Same behavior observed using two-screen support on Radeon Mobility 7500, Win XP
SP1.  Unique to Mozilla, other programs have no problems.

Reproduced with "Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4b)
Gecko/20030516 Mozilla Firebird/0.6" on Windows 2000 with Radeon 9700.  As
someone else said it's unique to Mozilla - other programs work fine.

I've seen this problem too. My solution was to get a screen with more resolution and get rid of the attached monitor.

BTW, I've run into several other problems that don't behave well with multi-screen setups. QuoteTracker and Tarantella do funny stuff with multiple monitors. Even the Sound Volume Control isn't well-behaved with attached monitors and that's a
Windows function. At any rate, I found that the menus would come up in the
upper right corner of the first monitor even though Firebird was in the second
screen.

I've encountered the same bug on a Mac OS X (Panther) PowerBook when using a
monitor attached to my laptop as a second screen. If I view a browser window in
the monitor and bring up the context menu or try to use an autom-complete widget
(for example in the URL bar) the menu comes up on my main laptop screen. This
happens in both Firefox 0.8 and Thunderbird 0.5.

I can confirm this behavior with "Mozilla/5.0 (Windows; U; Windows NT 5.1;
de-AT; rv:1.5) Gecko/20031007" on WinXP using an IBM Thinkpad with ATI drivers. 

The problem occurs only if the second screen is added/configured after the
current Mozilla session has been started. AFAIK Windows notifies applications
when the screen configuration changes. I presume that Mozilla doesn't
receive/handle this notification and caches the screen configuration on startup,
so that it doesn't know about the second screen.

[Joshua Marsh]

This bug still exists as I have been able to reproduce is with WinXP and Mozilla
1.7.  The same problem occurs in mail/chatzilla and all other mozilla apps that
use a menu. 

An idea as to the cause: Mozilla is using the size and location of the main
window to create and place the menu lists.  It should gather this information
dynamically from the current window position.  I've had problems doing this same
thing :)

Confirmed also in Thunderbird 0.7.2 and Firefox 0.9.2 (clone defect?)
Windows XP SP1, ATI Mobility Radeon 9600

I think that the applications are keying off the edges of the "original" display
(the one where the window first appeared), or perhaps off the main/#1 display
(the one with the taskbar). If the main display is on the right, menus appear on
its right edge. If it's on the left, menus appear on its right edge.

IE, Outlook, and Windows/MSN Messenger display menus correctly.

[A. Sapuntzakis]

doh!

if main/orginal display is on left, menus appear on its right edge
if     "           "     "  " right,  "     "     " its left    "

sorry 'bout that
