I have a Z22 and I recently got a Palm III (for $20). I tried installing the software for the III on my desktop - it was "Palm Desktop" and an upgrade to the OS. It seemed to conflict with the Z22 software. After installing, I could not hot sych the III and the previously working Palm Desktop (the z22 one) would not open. So in effect, neither of the Palms could connect. I uninstalled everything and reinstalled the Z22 software. Fortunately, it remembered all my data. The Z22 works normally now but I seem to have no way to get data from the computer into the III. Has anyone had experience with this? Thanks.
