Happy Day -- I uninstalled Logitech Setpoint and everything now works
-- the trackpad and the trackball work in excel, IE, etc. under xp/vmw/
osx. The old maxim really is so often true, "We have met the enemy,
and he is us".
Thanks so much Woody for your patience and indulgence with my problem;
without your replies and reassurances of how things are supposed to
work I would not have gotten here as soon as I have, if at all
(might've just learned to live with it). Since the trackball now
works perfectly in the way I wish to use it (i.e. I don't want to
attribute odd functionality to the buttons I use), it is not at all
apparent what value the Setpoint sw has at all.
Please accept my sincere gratitude and give yourself a few noble being
points.
