Further question - I tried the code you suggested immediately before the addobject in the procedure that adds the text box. VFP tells me that I have broken the rules with a "Statement is not a procedure" compiler error message. Where do I put the class definition code? Does it need to be a part of a library for all time or can it be limited to a project until I really understand what I am doing?
