I have read that the issue is related to the Toshiba Satellite Pro 6100
motherboard / keyboard / accupoint and that it is not related to the mouse. I
have used other types of mice and also just the built-in accupoint and the
problem remains. I have reinstalled XP and the problem remains.

I just have to live with it. Pressing ALT and using the keyboard, leaving
the mouse alone, seems to help a bit.
