>when I build an .EXE and run it the app starts in a window that is about half the size of the desk top. I would like it to be the full size of the desktop. Is that something that I need in the config file? Thanks for the help.

No, you don't need config file. When yr application starts put
foll statement
_screen.Windowstate=2 &&maximized

You can also use _screen.width, _screen.height etc...
