Rick and Ken,

I was at a demo of Delphi while VFP3 was still in beta, and one of the cool things it did was allow you to edit the class definitions while instances of the class existed. As soon as you saved changes in the designer the objects changed. It was pretty impressive. I have no idea it still works like that or not but it was a cool RAD feature to have available during development.

>Well it would get worse though - if you modify one of the base classes while you're editing one of the descendent classes you'd essentially be working on an invalid copy missing properties and methods possibly...
