Over the last few weeks every time I hotsync I get a log message along the following lines:

-- Date Book - Some handheld records were not copied to the Palm Desktop. Attempting to restore from the handheld. Desktop = 2018, Handheld = 5834 OK Date Book with 1 message(s)
OK Address Book -- To Do List ... does someone can help with this?
See if you can install dbScan: http://www.freewarepalm.com/utilities/db... This will clean up your DateBook.
Check your ToDo's to see if they all look readable on the Clie and on the Desktop. There may be 2 ToDo's that are corrupted.
Once all the corrupted entries are gone, everything should go back to normal.
