Ok, the little problem with this select - you should padr the result to some number, e.g.
SELECT padr(ALLTRIM(UPPER(Last_Name))+", "+ALLTRIM(UPPER(first_name)),40) as FullName,...

But it's unrelevant observation.

Can you check, if PatientDemo is used?

I would comment out CLOSE TABLES in Destroy (you don't need it if you have AutoClose set to .t.) and see, if it makes the difference. In any case, it sounds like these cursors are already somehow closed, which should not be. Can you find out, what method closes them?
