Something odd is happening and I thought I'd see if anyone can figure out why for me.
In my wife's user profile, if the screensaver comes on when IE or iTunes is running, then it won't go off again. The computer will then only respond to the option+apple+eject command to put it to sleep, then when I bring it out of sleep, the system goes back to normal.
Weird or what? Any idea why this would be happening?
