if you havnt figured it out already. open finder and you should be able to click on some preferences or some other thing (at the top) i cant tell you exactly cuz i'm at work and not on a mac right now, but you'll find a place where it'll actually ask you what you want in that shortcut menu. you'll find your apps box unchecked. sorry if thats a little unclear, i'll post in more detail later if you havnt solved it yet.
