>How to reassign?

Well, if this is the problem, it might be a good idea to use a completely different parent class, save the form and then re-assign to the correct parent class for the form type you are using. To change the parent class of a form (or most classes for that matter) use the class browser. Even if your form is SCX based, the class browser should open it. You could also hack the SCX/VCX. Try the class browser first.
