293789 - Multi-Monitor desktop "geography" detected only startup

Status: VERIFIED DUPLICATE of bug 245418

(Firefox :: Menus, defect)

Description

[Daniel Atallah]

It seems that Firefox detects the desktop size/shape only when it is started up.

What I'm seeing is that if I start a FF session when only one monitor is
activated (undocked laptop or over Remote Desktop, etc) and then I add another
monitor, and move the browser window to the new monitor, all popups (Menus, URL
typeahead fill) will appear in the wrong place (on the primary monitor).

I'll try to attach a screenshot.

Attachment: Screenshot demonstrating problem

Notice that I'm pressing the "Tools" menu in FF and the menu appears on the
wrong screen (the x offset for the tooltip window)

Sorry about the low quality image, it needed to be under 300K.

I can confirm this problem and it is annoying for laptop users who switch back
and forth from single to dual monitor configurations depending on whether they
are docked or not. The enumeration of a dual-headed setup to determine the
device contexts for each monitor seems to be done only once at Firefox startup.
This is incorrect.

A properly behaving Windows application will support handling the
WM_DISPLAYCHANGE message, and will enumerate the number of monitors when it
handles this message. Have a look at the Windows GDI manual entry on MSDN at
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdi/monitor_7gc4.asp

Isn't this bug 62395 and/or bug 245418?

I don't think it's 62395, though I have no way to verify that. It might be
245418, but it's hard to tell with all the chatter in it; it seems that bug
encompases more than one thing.

In any case, I would argue that this bug is much higher severity than 'normal';
firefox is boarderline unusable like this.

Thats it. I thought it would be patched in 1.0.2, but it was not. even in 1.0.7
it is't. It's a pitty that you are not able to use a wounderful Browser on two
screens proberly!

This does indeed look like a DUPLICATE of bug 245418, based on the discussion in that bug. If that is not the case, and if this bug is still visible in Firefox 3, then feel free to reopen it.
