Error in event log

I noticed this in the event log today:

Event code: 3005 
Event message: An unhandled exception has occurred.

Any ideas about a cause/corrective action?

It seems somehow the upload dialog initiated an upload with a previously used progress ID. Which version of FileVista do you use and can you reproduce the error?
