Someone, either from the KDE list, or the Debian-User list sent me a private
e-mail, and suggested making a change in /etc/X11/xorg.conf, and in the
section "InputDevice" for the "Generic Mouse". All I had to change was the
option line below from true to false.
Option "SendCoreEvents" "true" (change true to false)
A logout, followed by a login didn't resolve the problem, but a reboot fixed
it.
