Joe,
Drew Speedie talks about this 'feature' 'problem' (pick one) in his Visual MaxFrame docs. If you subclass an object with controls (as your form is) then what you have observed is correct. The CONTAINER (in this case the form) is subclassed but the controls are carried along. Your choice is to use this functionality or to subclass each type of control individually and re-build the frame.
