>I figured out a way to do this without the Class Designer but don't know if there are any disadvantages to it. I created a classlib using "create classlib mynewlib". I then opened both the original class library and the new one as tables then added records to the new class library and put the same data in the fields as the Class Designer does when you subclass. It works so far and will open in the designer fine after I did everything. Does anyone know if I'll run into a problem somewhere by doing it this way?

That should work.
