so my wife has a current iMac 27" i5. pre-installed with lion. Everything runs AWESOME!. it's fast, and works 100% of the time BUT... Although not a problem but more annoyance, when the iMac is asleep, and she presses say the space bar on her keyboard the iMac wakes.... normal right? good, that's not the problem. After it turns on at the sign in screen, if she has new email, the "new email" sound will play over, and over, and over, and over, and over, and over, and over, ..... you get the picture. so as it's playing over and over, she types her password and once she signs in, it stops. Anyone have a clue why or how to make this stop?
