It's not a big problem. Just requires an extra "Save As" step or two. I've been able to play with it enough to get what I need . Thanks for the heads up on 8-bit Screen 12 bitmaps. At least it's one more option.
And by the way, I spent a couple hours with the graphics tutor. Excellent presentation! It'll save me hours. I thought I was going crazy with the View and Window statements not making sense (with respect to defining the Window corners). Glad that it wasn't me.
