By any chance is your video card an ATI Radeon 9600?<!-/quote-!><hr size=0></blockquote>Yes, my video card is ATI Radeon 9600.<!-/quote-!><hr size=0></blockquote>Lucky guess on my part??? Not entirely. Just a day before, another Notation user isolated a very similar mouse problem to the ATI Radeon 9600.

Did you just recently start using the ATI Radeon 9600 video card, or did you recently update the driver?

I recommend that you visit the the ATI manufacturer web site to read up on this problem, and/or search around on Google to see how other folk are dealing with this problem.

Good luck!

Cheers
