Done! Now it takes longer for the map to show up but it's okay, I guess. How do I move the screen just a few pixels at a time in any direction. I have the arrow keys loaded in NextFrame event. But each time I try to move the map, it won't update with the new coordinates. I am so lost how he did that in the RPG. It still doesn't make any sense to me.
And I really appreciate your help on this.
Mark

Well, sure, the SpriteSurface does that.  It often needs you to paint
tiles that aren't on the screen yet, in case they are scrolled into
view.  Just modify your code to check that the Xpos and Ypos are in the
bounds of your array before you attempt to use them.
Best,
