>I've converted my project from vfp 3.0 to 5.0a. Now when I issue a ThisForm.release, the form doesn't go away; it did in 3.0. In development I simply issue a "clear all" in the command window and the form goes away, but this won't work in production. Anyone have any ideas?

Try release all in the command window. What is probably happening is that one of the properties in your form holds a reference to the form or one of its controls. Before the form can be released, you have to release that reference explicitly. You can do this in the form's release method.
