I have had the problem of my calendar data EXCEPT repeating events disappearing from my desktop. No other data (contacts, memos) seem to disappear. I am not doing anything unusual, just updating the desktop to synch to my Tungsten T.

However, I absolutely do not feel that these occurrences have to do with synching. They seem to happen when the desktop fails to close normally. I have never lost data in this manner due to synching.

I am using Desktop 4.1.4.
