Well, it looks like Handmark Express won't auto-update for me. Their customer support couldn't think of anything, so I though I'd turn to the experts (TCers, that is).

Using the standard Handmark Express software, every time it tried to perform an auto-update, the Treo simply performed a soft-reset. So Express sent me an updated version. This version just reverts back to the standard palm application list (which is interesting, because I have Z-launcher installed - it doesn't revert to Z-launcher).

This happens whether the software or the various channels is in RAM or on the card. It happens whether I was running 1.15 or 1.23, Treo 650 GSM.

Anybody have any suggestions? This is driving me nuts.
