    I've just recently noticed that my iMac display won't go to sleep, despite my energy settings should turn it off after 5 minutes of inactivity. The only difference I can think of is that instead of my Mighty Mouse, I now use a Microsoft standard USB mouse. Is the Microsoft mouse somehow keeping the iMac "active"? What else could just suddenly stop my iMac display from turning off automatically? Any advice is appreciated, thanks.

    Try it with your Magic Mouse. Disconnect the MS mouse and connect the  mouse and see if it helps. Repair your permissions with Disk Utility as well

    Fixed it! Thanks for the suggestions, it seems repairing the disk permissions did the trick.
