Hello all.

Newbie to the Blitz side of the house. Need some guidance:

I am trying to incorporate a 'main' program that uses mutex's to comm between multiple unique-function Blitz instances. That part I think (quote me) I have a handle on. What I don't have a clue about is have the 'main' load the background image (1024x768) and have the unique instances use viewports 'onto' that image. I've pretty well mangled my machine (the vid anyway) many times trying.

Any help in defining a method to do so would be appreciated.

FWIW I'm reading 6 USB devices, each instance doing their own thing (measuring and calcs) and have the main determine when they can draw. Experimenting on 'best method' for my app.

Thanx in advance,
Jim
