The second reason your Magic Mouse may be skipping or hesitating is that debris, dirt, dust, and gunk have become lodged in the mouse's optical sensor.
There's a simple fix for this, one that just requires giving the sensor a good cleaning. No disassembly is necessary. Simply turn the offending rodent over and use compressed air to blow out the gunk. If you don't have any compressed air on hand, just pucker up and blow into the sensor opening. When you're done, take a moment to clean your mouse pad or the desktop area where you use your Magic Mouse.
Even though the Magic Mouse uses optical tracking, it can still pick up debris that can prevent its tracking mechanism from working correctly. While it's possible that your Magic Mouse has a hardware problem, there still remains a more common reason for strange tracking behavior of your mouse, and that's a corrupt preference file that your Mac uses to configure the Magic Mouse when it's first powered on. There are a number of preference files related to the mouse that could be causing the problem.

I tried an external trackpad where I check to ignore the built in trackpad - same problem. I purchased an external mouse. The Senior Advisor was just a bully and hung up on me. I figured out the solution below for one application, but it might provide a more universal solution—disable the keyboard navigation key-combinations.
I think this is a general hardware issue.. However, specifically to my word processor: Nisus Writer Pro I discovered that 1. The cursor was jumping backward in the text to the last insertion point. There is a key-combination for this: Command [ , and to go forward to the next insertion point Command ], 3.
I can duplicate the issue if I touch the TrackPad, then hit either [ or ] the cursor will jump back to the last insertion point. The NisusWriter commands are very specific, the trackpad sequence is either bracket. I suspect that it might be happening anywhere there are similar key-combination shortcuts.
I hope this helps. Hope this helps some people. The Apple woman was really snarky and not helpful. I expressed frustration, she was just looking for an excuse to hang up on me.
