It would be helpful to know if it's just one file that's causing the 
problem.

Could you turn on Extended Logging, and see if it's uploading this file at 
the time when the user logs in? Is it a large file that would take some 
time to scan for changes? (e.g. > 20 MB)

Do you have any processes that modify the file at fixed times, e.g. 
during the night? Or do your users always close the application at the 
same time every day? Could you try changing your MinimumFileAge and 
MaxUploadWait settings?

Yes, snapshot is probably better, assuming that you can rely on it running 
every day, or arrange a systematic compare and warning if comparison 
fails.

Cheers, Chris.
