I have an app which is working fine when run from the develiopment version but if I run it as an exe, I cannot see anything.

I Know the app is running because I can do a Ctrl/Alt/Del and my 'Confirm you want to exit' message box comes up ok and I can exit from the app.

I have put in a few wait windows, ant they come up also.
but I cannot see anything.... e.g. if I run if from a Dos Prompt (Just by Typeing MYAPP.exe, the app runs (without a visible screen and I can see any wait windows)

This was working up to a few weeks ago but I have obviously done something.
(I've cjecked some other apps and they seem ok)

Anybody got any ideas ?

Regards,

Gerard
