I have a new macbook w/ leopard, and 3 or 4 times now, i have been in the middle of using various apps, when I notice that I can't type anything. For example, I'll try and enter text in google, while in safari, or I'll try and type in a document in Pages, and none of the keystrokes are registering. When this happens, the function keys don't work either, but the trackpad and it's button do work. I then do a restart of the computer, and then everything works ok again. Has anyone else had this happen? I'm wondering if I need to take the macbook in to apple for repair. Is it possible I've just accidentally pressed the wrong keystroke combination to disable the keyboard?
