Bruce,
Without seeing your overridden properties and without knowing what classes you are using it's impossible to give much more help.
If you can post a minimal fragment of the prg that does the DO FORM it might shed some light. Have you checked that you are not setting ReadOnly=.t. or .Enabled=.f. on the controls?
Other than that you can fire up the debugger and look at the object properties at runtime when it's working and when it's not to see the difference.
>It is like I am viewing the form in preview mode when trying to access it from the program. The input fields are not active, and not even the buttons work. Can't depress the buttons. The only button that works is the "X" shut down button.
