Thanks Rafe.  Mine looked smooth as silk too.  I couldn't figure out what I
was suppose to be seeing and wasn't.  Now I get it.

Actually, no-one COULD edit photos at "256 colors" but they might try at 16
bit.  At 16 bit  the "topo map" effect" is clearly visible too.

I think you found the problem.
