I commiserate with you. I also experience this frustrating phenomenon.
From the considerable number of replys you have received in regard to this issue...it would appear that a solution, currently, eludes us all......
I use an optical mouse...not the remote kind.
My system (AMD/ATI) is quite current, my only bottleneck being RAM.

We can only hope that either the Developers rectify this issue with a patch or some technically minded individual explores it for us...technically challenged types


.....anyone?
