"This entry no longer exists" message
                    I am having trouble with my notes in word documents once I export my Library to back it up.  When I return to the document, and when I change, add, o delete a note, it then asks me for every note in the document whether I want to delete the selection because it no longer exists in the database.  Why is it doing that?  And how can I stop it?
