got a new MacBook Pro recently and just now noticing something pretty odd... if iTunes is playing and I hit the play/pause key (F8) the entire keyboard will go dark, but only if I'm pausing. it doesn't do it when I'm hitting the button to resume a song, only when I'm using it to pause one. the backlight sometimes takes minutes to come back on, at random, and sometimes it doesn't and I just have to turn it back on myself. update: I've found that it's not just the shortcut keys — the backlighting turns off even when I go into iTunes and press the spacebar to pause or just press the actual button in iTunes. pretty odd, haha. any ideas? thanks!
