Just migrated from Entourage to Mail, Address Book and iCal. I like the abiility to share the calendar on-line and it just makes sense to use Apple applications on a Mac. Anyway - Address Book seems to be really slow. When editing a contact or searching for a name, it takes about 5-6 seconds to find the name (800 entries). When I type new information the screen is about 3 seconds behind my keystrokes. I've repaired permissions, am running 10.3.7 and have plenty of RAM. Any ideas?
