I think this is a problem that started with Snow Leopard and I'm wondering if there's a solution to it yet. Right now I have iTunes open playing music, as well as a paused video in VLC. When I press the play/pause button (F8) on my black late 2008 MacBook, it pauses iTunes but then unpauses the VLC video. This is obviously totally unwanted behavior. How do I fix this so that this button only controls one app at a time?
