Let's start all over again ... sorry for the bonehead error yesterday - been working those 25 hour days for the past couple of weeks - shows!
"I'm using a 1.25 GHz PowerPC G4 ... before my current LEOPARD instillation, my Address Book worked like a charm - now I get a "You cannot use this version of the application Address Book with this version of Mac OS X" message box. However, IF I search out a name in my Address Book, it shows up as a 'contact' - and upon clicking on that, I get the Address Book in it's full (operational) glory. What's up with that? How do I get Address Book to come up each time it's summoned - minus the work around?!
