Thank you vary much Christopher, you've solved it!!  I had to set the
accuray to 0.000001 to be rid of all the artifacts, but its fixed.  Huzzar!

I especially appreciate the explanation.  As I understand it, the accuracy
setting is like increasing the "Zoom" on the ray tracings engine.

I'll post the finished image when its rendered ( probably take most of the
weekend ) so you can see what you've helped along.

Thanks again.
