Since last Sunday, the Calendar on my Palm Tungsten E2 has not hotsynced properly with my computer (iBook G4 running 10.4.11). Everything else syncs just fine; if I tell the Hotsync Manager to skip the Calendar, all else works. But with the Calendar, it displays the Hotsync window on the Macintosh screen for a while, then it blanks out and vanishes without completing. On my handheld, the screen stays frozen on the claim that it is syncing the calendar; I have to hit cancel and reset to get it to work again. When I do, I find that all my new calendar data, entered into the handheld, is still there.
I've tried resetting the handheld and restarting the computer; installing the latest Palm Desktop software (4.2.1); deleting old data from the handheld in case I was using too much memory (edited to add: and then trying "Handheld overwrites Macintosh"); and trying to sync with Mac's iSync, which also failed on the calendar. Any other ideas would be appreciated.
