I woke my Intel iMac, and Safari wasn't responding, and Mail did the same thing. I force quit them and everything seemed fine, except I lost my Address Book Contacts. I sync my iMac with .mac along with my Powerbook. I had thought that going into System Preferences and syncing manually would fix it, but for not. I know that I can just copy the Address Book on the Powerbook and remake it on the iMac, but I thought that .mac syncing would see the empty card on the iMac and fix it. I am also a little concerned that I had this data loss after waking from sleep. Do any of these symptoms seems familiar. Should I be looking for another "hidden" problem... Cheers in advance.
