Mouse skipping, any fixes?
 

So I've read other peoples issues with it, and I have no idea why, but mine is EXTREME skipping. I've deleted that one kext, appleuserupstream.kext, but I still get this. What else could be causing that, and what can be done to fix it?

Update: Only my Wireless Microsoft X8 skips, my wired old MS mouse doesn't do that. Why?

Nobody can help me?

have you tried their newest intellipoint for the mouse?

7.1? Yeah. Still nothing.
