This isn't actually for myself, but for a colleage. However, it has interested me so much, that I really want to find out exactly what is going on. My understanding was that instance of the class was created. I guess I hadn't REALLY thought about what an instance was. It would seem that an instance is simply a temporary subclass of the object. The name of the class (as in DEFINE CLASS ClassName AS ParentClass) being the name property of the "instance" on the form.

Would you agree with this?
