Scott,

Thanks for your response.

However, when I use your "circle" above I get an opaque circle filled 
with the color yellow. That was why I inserted the reset the 
templateGraphic *before* creating the circle graphic--but only with 
this stack. I suspect there is something corrupted in my stack--how 
many times has this easy assumption turned out to be wrong?

I can, as I said, set the foregoundcolor to black, but I should have 
thought that that would be the default value--the value you would get 
after one "reset the templateGraphic".

The only way I can think of testing this issue is to examine the 
default values of the templategraphic, and this I don't see how to do.
