You're right, of course ... encapsulation is definitely the preferred way.

Probably when we first implemented the FormsHandler way of doing it, we didn't take the time to find the WndProc method, as you did. The whole idea of a FormsHandler is how we implemented this kind of functionality in our old VFP app, so I guess we just carried the idea forward. Unfortunately, with our methodology, you *do* have to remember to add the newly instantiated Form to the FormsHandler, you're screwed if you don't do that. But that's all you have to remember ... everything takes care of itself after that.

Anywho ... this has been a good discussion. Thanks!
