As another datapoint, I have observed a different but perhaps related
problem with Emacs (both 21.2 and 20.7) under KDE (2.2.2): when I
click on a menu bar label in Emacs and then press `Ctrl-TAB' (the
KDE keyboard shortcut to change the virtual desktop/workspace) while
the Emacs menu is displayed, the keyboard locks up.  I haven't been
able to replicate this behavior with other apps in KDE (they simply
block switching of the desktop, as described above).  On the other
hand, it seems similar to a known KDE bug and has a similar
workaround, i.e., clicking on the border of an active window (see
e.g. bugs.kde.org/db/29/29926.html).
