I just bought a wireless mighty mouse and it's been behaving erratically... Turn it on after a fresh boot it works fine, but after a while it's started to act incredibly erratic under both OS X and Windows XP (bootcamp)... Anyone experienced the same thing by any chance? By erratic I mean the cursor movement doesn't correspond to the movement of the mouse itself - to the point where moving the mouse slightly left will send the cursor all the way to the right hand side of the screen, and stuff like that... I can't quite put my finger on it atm, but there's definitely a point at which it goes from working perfectly fine to very erratic... will post back if I figure out what it seems to be... Any tips or help would be appreciated!
