Ok here's the deal:

Axim 400 on Win98 PC/Outlook 2K with Active Sync 3.7

I start off in the morning, let the PC boot and then connect my Axim to sync up. Everything syncs up fine and stays sync for 1/2 hour or so. After this period I start noticing that my e-mails, task etc are no longer syncing. (sp?)

I go to the green sync icon on the task bar and by leaving the mouse over it a few seconds, the message "Not connected" appears.

If I disconnect the Axim from the sync cable, the sync icon goes grey and by re-connecting the Axim it won't connect back up unless I do a soft reset on the unit.
At this point I can go on for another 1/2 hour or so and wham same thing.

Anyone... help

Axim 400, Vicking 256 SD, Screenwright shield, Covertec Case on it's way.

oK, Self fixed or at least for now....

Delete the parternship and re-established it. Everything seems to be working ok for the past few hours.

Activesink, as someone else referred to it is about right...
