>This should be simple. I've tracked it down to the WindowType property. I have a form (created through AddObject) that, when Modeless, can be closed using the close button on the title bar in the upper right hand corner of the form. When the form is Modal, I click on the close button and it just turns grey and the screen is still displayed and active.

Firstly, it's no problem to close modal form. You could try to 'strengthen' code by Release Thisform. In some situations, the failure to close normally may indicate that some form property holds reference to some object and all these references should be set to .NULL. in Form.Destroy event.
