About to purchase a new iMac I think.... I love the Magic Mouse but had one before for the MBP I am using now and it worked perfectly for about 6 months and then just stopped one day. I could not get it to work again and I believe short of wiping the system and reinstalling all my software would not have got it recognizing my MBP again. So ARE there any known issues with the magic mouse and the iMac? Last but not least, I use a mouse with my MBP. I have not been able to manage the track pad and just keep going back to a wireless mouse. One day while playing at the Apple store, I DID use a USB trackpad and they must have had it set up differently than the defaults for i had NO problem using that one......it mimicked the magic mouse movements and i loved it but i have never been able to mimic it on my MBP.....wish i could. Anyhow, are there known issues with this magic mouse suddenly not working on the iMac as a rule? T.I.A.
