>Good question. I have not set anything with regards to threading in the .net dll. By default is this running in the same thread or not? I guess I want the .net form to close when the foxpro app closes so it should run in the same thread, correct?

If you're callin the form directly, then it's running on the same thread most likely. The form will be modal. If it's not modal, then it's running on a separate thread with its own event loop. Unlikely if you don't remember doing this.
