Switching between applications is broken after some time
I am really at a loss here...
Somehow my installation of KDE got corrupt, after I work for some time with
my KDE Desktop, switching between applications using <ALT> <TAB> is broken
and behaves really strange.
When I press <ALT><TAB>, the Application-Menu with "move", "resize", ... is
shown instead of the dialog with all the application icons in the center of
the screen. Even stranger, if I press a mouse button while still holding
<ALT>, the correct dialog is shown and I can step through the applications
by pressing <TAB> while holding <ALT> down and switch to any application
when releasing <ALT>, just as I would expect.
This is really annoying, as I use my PC very "keyboard oriented" and I am
stunned every time this behaves so strange.
After I restart the machine, it works for some time (e.g. 1 hour, ...).
Using <ALT><TAB> worked before even if the machine was running for a long
time, I am not sure what I did to cause this.
I upgraded to the Nvidia-X Drivers recently, could this be the cause for
KDE 3.1.2 Debian/unstable, X-Free 4.3.0
Any hint what might be wrong or where I should start looking? I already
searched with google and bugs.kde.org, nothing!
