Why does the menubar hide when I'm in iTunes? Often when I'm using iTunes 10.4, the menubar will hide and show like the dock does when you set it that way. I don't know of any settings that allow for that to happen on the menubar. Is it a bug or a setting that I accidentaly changed?
It sounds like you're running iTunes in full screen mode if you're on Lion. In the top right corner you should have a button with two arrows that allows you to switch between full screen mode and regular mode.
