Ok, very weird: My delete key doesn't work. Brand new 17" C2D MBP. Got it last Thursday. Has worked perfectly. This afternoon, after playing with it all day, my delete key does nothing. The weird part: in Firefox, the delete key works if I hold down Shift. In some other apps, it doesn't work even with the Shift key modifier. I have restarted and run Onyx and AppleJack. Nothing. Ideas?
