Tagging M14 Assigned for now so Bugzilla won't send me nastygrams

This is also an issue for Windows 98 users... leaving it up to sdagley to futz
with platform, OS, [PP] if so desired... Changing QA contact to claudius, who
has a multiple monitor Mac OS computer, and adding self to cc: list to verify
functionality on Windows 98.

Moving to M18 to sync with #4252 and assigning to damn as I believe he owns all 
things window positioning related (or knows who does)

mass-moving all bugs to m21 that are not dofood+, or nsbeta2+

Probably related to this, with M18, the first time I start the browser 
everything works fine except for the badly positioned windows.

On the second start the main browser window is openened at the 
combined size of the both screens, positioned in the place where the last 
browser window was, displaying only white and then the browser hangs.

This essentially renders M18 totally useless on my machine. I don't 
remember older milestones exhibiting the problem and the final version 
of Netscape 6 works just fine.

I'd up the severity.

Jussi: the symptoms you're describing generally imply damaged UI files -- usually 
a missing CSS file. I don't know why this happens only after your second launch. 
Big blank windows are a crummy way to inform the user of a problem like that, but 
that's how it works.

I'm having trouble with un-smart window positioning, too.  When I use
my PowerBook with an external display, I put Mozilla windows over there.
When I disconnect, even after restarting, it doesn't bother to put windows
on my (only) display.

With browser windows, they're staggered, so if I create enough of them
(usually 10-15), one will appear that I can grab the title bar of, and
close the rest, and I'm ok.  The right-click on image -> Properties window
is almost completely off-screen, though, and I can't think of any way to
get it back now, or even close it (it won't respond to cmd-W).

(Bug 141204 might be related, but it's specifically for re-detecting
screens while Mozilla is running; this one doesn't correct itself after
restarting Mozilla.)

Old bug, is this a problem on OS X?

Comment 9

[Dan M]

Ha! Yeah, this one's been fixed forever. See for example bug 162090, which
specifically addresses the issue in comment 7. Note there is still bug 98830
with placement of popup windows (like menus) on multiple monitor Windows systems.
