I did notice the problem only happens when the surface beyond has a normal.
You are right that it may be reversing the normal, I at first thought it was
just shifting it.  I'm beginning to think that this must be a POV-Ray bug,
but if it is, I need to find a work-around for my scene.  I can't get rid
of the "normal" on the surface behind the object, because that is water and
I am using the normal to generate the waves.  I have hundreds of the
"electron" objects in the scene.  The only thing I can think of is to
#declare a different object for every orientation I need since the
unrotated objects seem to render fine.
