Hey, I've got a problem with address book which I believe is originating from mail. For some of my contacts I only like to have their first name (or don't have their last name) such as mum & dad (yeh I'm aussie ), my girlfriends name etc and whenever I email them their name appears twice in their contact card in address book. Ie, Mum will become Mum Mum. I delete the second appearance and It just comes back next time I email them. I have tried permissions, onyx etc but can't solve it. Is anyone else having these problems? Thanks I've had this problem ever since I got my macbook in may and can't find anywhere that discusses it.
