[Not sure if this is the same problem, as this bug is from 2008 and it only
happended to me since KDE 4.3. But the symptoms look the same, so...

I can ALWAYS reproduce this bug by pressing the "mouse gestures button" (right
mouse button) too long without introducing a real gesture, e.g. by pressing it
for a second or so within any program window that would usually show a context
menu upon right mouse click.
It seems that some window / desktop component grabs the mouse button input and
fails to release it. I can move the mouse pointer, but usually only the taskbar
will take any clicks. So I can open the start menu, but have to use the
keyboard to close the KDE session. I can also always use the keyboard to close
the current programm via Alt+F4.
Sometimes mouse buttons don't get trapped within the taskbar, but some other
KDE component. The folder view plasmoid on the desktop is a candidate for this.
I can then use the mouse to paint funny selection frames within that plasmoid,
but there's no way to click on the start menu.
Sometimes (seen in Vice) the application window itself seems to lock the mouse.
Then I can click _anywhere_ on the screen, e.g. left click on the start menu
button, and it will always show the Vice menu.
I'm using KDE 4.3 on Gentoo x86_64, this bug has been confirmed by other Gentoo
users having mouse gestures enabled. Still happens in KDE 4.4. I'm not using
Xinerama and this was a "clean" KDE 4 install, no ~/.kde update from 3.5.

This is by far the most annoying bug I've ever seen in KDE, and it has thrown
me back to the good old Windows-like "save early, save often". It's a pain.
