282001 - Only one browser window may ever be opened

Status: RESOLVED INVALID

(SeaMonkey :: General, defect)

Description

[David D. Kilzer (ddk)]

Tonight I upgraded Mozilla on my Win XP SP1 PC from version 1.7.2 to 1.7.5.  I
did NOT uninstall 1.7.2 first, but instead ran the installer for 1.7.5 and let
it clean up the previous installation.  Note that I did have a version of
LiveHttpHeaders installed with 1.7.2.

After installing, the new version of Mozilla 1.7.5 started up just fine. 
However, I couldn't open a second browser window (or the Profile Manager) while
the first browser window was open.  Double-clicking on a short-cut, Ctrl-N and
selecting File->New->Navigator Window don't have any effect.

I tried uninstalling 1.7.5, rebooting, then reinstalling 1.7.5, but this didn't
work.  I had the same issues as above.

After playing some more with 1.7.5, I noticed that SOMETIMES, when the "X" box
in the upper right-hand corner of the Window is used to close the single browser
window, the "mozilla.exe" process won't exit (by looking at the Task Manager's
process list).  Killing this process is the only way to reopen a new browser
window again.  If old process isn't killed, double-clicking on the "Mozilla"
icon does nothing.  (The cursor changes to the hourglass cursor, but then
changes back as soon as the mouse is moved.)

The "mozilla.exe" process has ALWAYS exited when File-Exit is used.

I even tried uninstalling 1.7.5, rebooting, and reinstalling 1.7.5 a third time,
but the behavior persists.  Note that I also have Firefox 1.0 installed on this PC.

It doesn't matter whether I install with "Quick Launch" enabled or not.

Well, I feel silly now.  After re-installing a new version of LiveHttpHeaders
(0.10), Mozilla is working properly again.

So if anyone wants to reproduce this issue (roughly speaking):

1. Install Mozilla 1.7.2.
2. Install LiveHttpHeaders 0.9.
3. Install Mozilla 1.7.5.

Pain.

This was not a Mozilla bug, so it could not be "fixed".
