I guess I haven't used the iBook in a couple weeks and when I got on tonight I had several updates....but the Quicktime update is giving me fits. It is calling for a registration number, and then says if you don't have it leave it blank....well it is not accepting blank. I really don't think I ever registered with Quicktime, each time it would pop up I would bypass that step.....How/where will I find a number to register? Any clues will be greatly appreciated. It is possible I don't really need the update anyway. I don't believe I've used Quicktime that much....thanks, trish
