Dear Dick

You are the first person I have heard of who has had this situation happen to them, are you sure that the calendar files are NOT on a Network drive or a USB drive which has an intermittent connection?

Dear Jim

No, all files are on my computer with back up files on a Seagate external storage drive.

Dear Dick

Is there some backup program running and if so, exclude Sidekick data from the backup and do it manually WHEN SIDEKICK IS CLOSED.
Not all programs are able to be backed up when they are running and if forced to do so, data becomes corrupt or unavailable.
Those are the only thougts I have on that score, let me know if that method works.

You can usually set up a profile in a backup so that you can double-click an icon to backup when you have finished working in a program.

I used SecondCopy
http://www.secondcopy.com/
for 15 years on both Calendar and Cardfile backups and did not lose any data. At times SecondCopy would put up a info box telling me that it had failed to backup a file because it was in use and that it would try again in 30 secs. This was because I was adding data at the time and Sidekick had locked the file. Once I stopped adding the data and the 30 secs were up it would succesfully perform the backup.
