Since upgrading to Mountain Lion I have experienced frequent and inconsistant tracking from my Magic Mouse. It will work fine and then out of no where, and without any connection to a particular app or process (that I can identify) it will begin stop moving or move in a very jittery fashion. I'm also experiencing Bluetooth connection loss with the mouse from time to time out of nowhere. I cleaned the mouse and even went to so far as to replace it with another, brand new Magic Mouse and have seen the same problem.


I have also tried resetting PRAM and SMC.


Anyone else experiencing this or a similar issue? Have any suggestions of things to try?
