A private e-mail sent to me from someone on either the Debian-User list, or
the KDE list, has enabled me to resolve the mouse problem.
All I had to do was edit a line in /etc/X11/xorg.conf relating to the mouse.
Section "InputDevice" "Generic Mouse"
Option "SendCoreEvents" "true"
I changed the above line from "true" to "false", as suggested, and now the
mouse works as it always has done in the past.
Having made the changes, a logout, followed by logging back in to KDE did not
fix the problem. A reboot was necessary.
Nigel.
