Problem: Was surfing on my Mac Mini when the cursor starts acting erratically, when i try to move it, it jumps all over the screen.
I have tried repairing permissions using disk utility, resetting the 'pram', used clamXav to scan for virus. starting in safe mode to repair permissions.
Don't think it is the mouse its self, used it on Macbook and it's fine
Any idea what it might be and any fixes.
