Michelle,
If you open a form in the class browser you can use the Redefine button to change the class it's based on.
Once you start finding cool stuff in places the easiest thing to do is to build it into your classes as appropriate.
>Cool. The trouble, though, is deciding which class to use. I subclassed all the VFP base classes and did some forms with those (Unfortunately, the forms themselves are baseclass ones). Now I got directed to that Fastwrite site, and found their cool class lib. So I'd like to go back and redo the forms with those. But then what happens if I find even cooler classes down the road?
