I've upgraded my PC to Vista recently and I have set up the Bluetooth connection to my Treo 750 and also the sync setup using MS sync center. It syncs the phone to my PC after the initial setup, but after that I can never re-connect my phone to the Sync Center. The bluetooth connection works and the pc and the Treo pair up, but the Treo remains "disconnected" in Sync Center. In frustration, I deleted the pairing on the BT and from the Sync Center and re-setup the connection and it all worked, but then when I retry the connection, the Treo doesn't connect to MS Sync Center to sync my outlook. Any ideas why and how to resolve? Thanks in advance!
