David,
Just open the CB, the Open the form in the CB (use the cbo to change from classlib to form), then click the Redefine button, pick the other classlib/class you want to it to be derived from.

I think the class browser may allow you to Redefine a form like it does for classes.>
>Just started getting into the CB. Not sure how I would use the CB to redefine a form (as opposed to a form class), any clue would be greatly appreciated.
