My Apple Magic Mouse has lost the ability to scroll the way it used to. When I open the mouse pane in System Preferences, the magic mouse options and video examples no longer display; just scrolling and tracking speed. I changed batteries, then also switched mice with a colleague, but still no horizontal or inertia scrolling, etc. I have tried restoring the PRAM several times, trashed the preference logs, etc, even reinstalled the system software.


I'm using a MacBook Pro withSnow Leopard. I had previously downloaded USB Overdrive, and read somewhere that it could be the cause. I got rid of USB Overdrive, but my mouse still doesn't behave the way it used to. Any suggestions?

MacBook Pro, Mac OS X (10.6.8), Apple Magic Mouse

    I got rid of USB Overdrive


    And all its preference files?  Repaired permissions?
