With the understanding that I am a first time Palm OS user, this could be an easily answered question. When I try to hotsync my Pismo 500 (Powerbook) with my Treo 300 via the IR ports, my Treo flashes on with a "Waiting for Sender . . . " messsage and then returns to the contact book w/o ever syncing. I am using Palm Desktop 4.0. Any clues??
