I can't find a common pattern, but at least once daily, hotsync between the PC and Treo refuses to connect. For no discernible reason, they won't talk to each other. I've tried shutting down and restarting the PC's hotsync, soft resetting the Treo, looking in the task manager to see if for some bizarre reason I have more than one copy of hotsync running - all to no avail. The problem seems to be PC based, in that after I reboot (a major project over here), everything works well. I only have one version of hotsync on my PC. Has any one else experienced this? Thanks for any input.
