RORO01  A NOTE OF CAUTION. The Read Me attached to this download says:

"Important: Bug in OS X 10.4 may lead to loss of Address Book data

There were a few reports of users completely losing the contents of their Address Book while working with Serial Mail. The problem is not related to Serial Mail, it is due to a bug in Mac OS X, presumably the SyncService. There are many reports of this problem in the Apple discussion group. From these reports it appears that the problem comes form a sync (like iSync) conflicting with another application trying to access the Address Book.

See http://discussions.apple.com/message.jspa?messageID=3028664

Since for most of us the Address Book database is one of the most valuable data, please backup your Address Book database. It is just one click to the File menu of the Address Book application."
