Hi, Jay -
You really did not give us much information. It sounds like your application executable does not open maximized as desired, if I understand you correctly.
The WindowState property of your window describes the initial state of the window when it opens. In the Window Painter, change this property in your window to Maximized! and the window should always open in a maximized state.
The PB Help topic for WindowState tells you how to code this behavior if you do not wish to set this property in the painter. In the window's Open event, code: This.WindowState = Maximized!
