I created a class for a lookup form that is used through out an application. When I want to display the model form I just issue a oCal.Show(). The form displays ok then when a button is clicked it issues a THISFORM.visible = .F. and should continue program execution.

Needless to say the main form display cannot be accessed now, the screen just beeps whenever I try to select anything on it. I do not want to release the oCal object, but I do want to return control to he calling program. What am I missing?
