My magic mouse is having some serious issues tracking. For a little background, I'd been using a 3 year old MBP for awhile, and when I brought it to apple to get the cd drive fixed, they told me they were unable to do so and gave me a new MBP (awesome). Now using my Magic Mouse for the first time with it, I'm having some serious issues tracking. It's almost as if there's bluetooth interference (sometimes it works fine, sometimes it barely works at all), but I can't figure out what would be causing it. It's the same set up as my other computer which worked fine. The only other bluetooth device I have is an apple keyboard and the mouse is only about 2 feet from the computer. Any help, anyone? Are the new mbp's having issues with bluetooth?
