It can't be easily solved. The T3 had all of its databases in RAM all of the time. This meant if you lost power, they'd be erased and you'd have to restore from HotSync or a backup. Since the Treo 650, Palm devices have used non-volatile storage where databases are read from Flash memory into RAM temporarily, then written back out to Flash. This means that when you lose power, you don't lost your data. However, the new layer of access does slow down some operations. -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/
