Jumpy mouse in CS2

Hi all,

I have recently switched from PC's to Mac. I am a photographer and use Photoshop daily. I have a Microsoft 3-button mouse, which works fine with most apps in the Mac.

My problem is that when I use Photoshop, if I am doing careful editing work, such as making a selection with the lasso tool, the cursor will jump short distances randomly. Compared to the way that it behaved on the PC, it is very unpredictable and this is obviously frustrating. I have ordered a replacement Microsoft Intellimouse, which I have heard good things about even from Mac users. Apparently the new Mighty Mouse doesn't quite live up to it's name.

I would love to hear your ideas on solving this problem.

Thanks,

PS: I have tried turning the mouse sensitivity down, and this has helped a little bit, but not enough.

Just for the record and to better help you, which Mac model is it and the OS version like say 10.4.9.
