Status: RESOLVED FIXED

(Core :: XUL, defect)

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.1) Gecko/20020826

After a certain sequence of events, clicking the zoom button results in an
impossibly small window (1 pixel wide, ~15 pixels high).  There is no widget to
resize the window to make it larger.  Closing this window saves the window size
making all further windows nearly impossible to work with.  Restarting the
application will not help the user!

This is observed on Mac OS X 10.2

Reproducible: Always

Steps to Reproduce:
1. Launch Mozilla
2. Click the zoom button of the window that appears.
3. Close the browser window.
4. Open a new browser window.
5. Click the zoom button.
Actual Results:  
You receive an impossibly small window.  Unless you discover the difficult UI
trick or know how to edit (or delete) your profile directly, you cannot use
Mozilla ever again.

Expected Results:  
Check the Mac UI guidelines!

Well-behaved Mac OS applications behave as follows.  This is a little different
from Windows!  However, ANYTHING IS BETTER. ;-)

* New windows open as the "standard size" which is determined by the
application.  This is generally independent of any user preferences, but it's up
to the application.

* If the user moves or resizes a window significiantly (>= 7 pixels) that
becomes the "user state".  This is what the application stores and remembers
between usages.

* While in the user state, clicking the zoom button sets the window to the
standard state, moving it as little as possible.

* While in the standard state, clicking the zoom button sets the window to the
user state.



There is a way to recover without directly editing your profile.  If you look at
the window created by this process, it will be a thin vertical line (usually in
the upper-left part of the screen).  It will have a darker pixel or two near the
bottom that seems to segment the window.  Clicking or double-clicking (I'm not
exactly sure) a certain pixel in that area will get the window back to a minimum
usable size.  It takes patience, but can be done within a couple of minutes with
practice.  Also, don't touch the zoom button!

I think this may be a dup. Adding DUPEME/qawanted, reassigning to XP
Toolkit/Widgets, and reducing severity to major.

I'm the reporter of this bug, and it's fixed for me as of 1.2.
