You must set the titlebar on your forms to 0 to hide the title bar. For the main screen, make a dummy.exe with this as the main.prg (and only program in the exe for example purposes):

*main.prg to hide toolbar and menu
SET SYSMENU OFF
_screen.titlebar=0
HIDE WINDOW standard
CLEAR
WAIT WINDOW "this is the app with no menu and no titlebar"
SET SYSMENU ON
_screen.titlebar=1
ACTIVATE WINDOW standard
WAIT WINDOW "this is the app normal"
RETURN

Oops, I think I misunderstood. Are you saying that when you run your .exe your exe runs but there is NO title and form? Just a blank screen appears and you are wondering what is wrong? If so, put in your main.prg something like the following:

DO FORM <yourform>
READ EVENTS

Then in your form, in the unload event put a CLEAR EVENTS if it is a one form app.
