Hi Sierraken, try it with Steve' s CircleFill:

Thanks Petr! I need to learn how to use that code.

LOL B+! Great job.

Code: [Select]
        ‘ CIRCLE (x + 400, y + 300), 30, _RGB32(c1, c2, c3)
        CircleFill x + 400, y + 300, 30, _RGB32(c1, c2, c3)
As you can see from Petr’s replacement above, it’s usually just as simple as using the sub name CircleFill instead of using Circle.  Just don’t put the X/Y coordinates in parentheses.
