I've just bought a Treo 600 to go alongside (for the time being) a Tungsten T2. I'd like to sync both devices with Palm Desktop (latest version) but seem to be having trouble doing so - for one thing, it keeps creating a new Contacts database whenever I open the Desktop and renaming the old one (or something like that!). Because I'll be sharing the treo with my wife, I created a new user for the Treo on the Palm Desktop.

Am I trying to do the impossible? Should I have just used the same user for both devices? Any help most appreciated.
