>>Hi Bruce,

>>I haven't tested this with a top-level form, but I believe that modality only applies to within the particular thread, and not outside it. You can demonstrate this by simply opening up one of VFP's dialogs, such as "Open". While you can't access anything else with VFP, you can feeling move to other applications. I suspect that this explains the behavior that's been reported here.

>Yes, that could be it. David, are you launching a modal within the TL app? That will keep it open, though not very functional, without a READ EVENTS. As soon as you close the modal - zap! - you app is history.

I have a single Top Level Form set as modal, and called from my Main prg. It has a number of pages and although I call other forms (all modal) "in Top Level form", my top level form does not close. Exiting the form exits the application, so perhaps that is why it is working. I have recently had problems trying to place a non-modal form over the top of my Top Level Form, and this could be the reason.
