223974 - Alt-tab switching leaves focus on previous Mozilla window

Status: RESOLVED EXPIRED

(Core :: DOM: UI Events & Focus Handling, defect)

Description

[Scott Anderson]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20031010 Debian/1.4-6
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20031010 Debian/1.4-6

After a certain amount of time running Mozilla (lots of opening of new tabs,
windows, etc.), it will develop a problem with focus. When switching from one
Mozilla window to another (alt-tab), the focus will be left on the old window
and no keyboard navigation or hotkeys will work - UNTIL the mouse is used to
click on the displayed window, or the down arrow key is pressed. After one of
these two corrective measures, all keyboard navigation and hotkeys work normally.

Sometimes when the focus is left on the old window, all keystrokes will be used
on the old window (this is really fun with ctrl-w :-P ), but sometimes not. The
focus issue only seems to occur when switching from Mozilla windows to other
Mozilla windows.

Reproducible: Sometimes

Steps to Reproduce:
Never after a fresh Mozilla is started; after a while something changes and the
issue presents itself.

After some additional playing around, I've discovered that the buggy state only
exists for a single window. Other windows receive the focus fine. If I close the
"bad" window, the problem goes away until it crops up another time.

In a seemingly related bug:

Viewing this page causes the scroll wheel not to work, until after a few down
arrow keypresses.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
