Problem... I've tried to change the backgound of the main window by the following
with _screen
.backcolor = rgb(0,0,0)
.forecolor = rgb(255,255,0)
endwith

Makes the screen black with yellow print in the devloper, but when I build the project and insert this code in the "main program" so that it configures the window, it will set the main window to black, but not allow anything to print on the window. It has me puzzled as to what I'm doing wrong. It seems that if it works in the developer, it should work the same in the application.

I'm also wondering how to put a bitmap image on the main screen so that when an application opens it appears in the main window.
