Anyone having an issues where their iMac display will turn off (computer still awake) but won't come back on again after you move/click the mouse or press a key on the keyboard? I am using the apple bluetooth keyboard/magic mouse that came with my iMac. It is the Mid-2010 model. I've tried re-installing but the issue still occurs. Any ideas? I have attached my "energy saver" settings incase they are needed. Also, "Allow bluetooth devices to wake this computer" is checked in the bluetooth pref. pane.
