My magic mouse no longer responds to touch. I can move the cursor around and left click, but nothing that requires the touch surface. I do remember dropping it from the desk to the floor, but I'm not sure if that's when it went out because I had been using the magic trackpad for a while before going back to the mouse. I have tried all the usual things like removing and adding it as a device and rebooting. Has anyone seen any articles about this or know of any way to try and address this issue?
