I have palm Vx running 3.2. Just got Treo600 running 5.1.

Trying to use both on the same Windows XP system.

Can I use the software that came with the Treo to work with both the Vx and the Treo? I am using the same port with different user names for each device.

If so, I assume I would have to delete the older Vx software first.

I tired installing the Treo software where it overwrote the Vx software but I got the "809" error (did not sync).

Had to start over and reinstall the Vx software to sync the Vx. Now that works again, but I am afraid to do anything else for fear of making matters worse.
