Running VAM 5.0 front end app to MS/SQL 6.5 backend. I have a form that has many views (10-15). I am looking for ideas as to what could cause an intermittent, but eventually, nearly certain 'Invalid connection' error when I try to close the form?

I have tried every combination that I could think of, from making the connections non-shared to increasing the connection timeout and other setting, with little luck.

Any suggestions?
