More than sure. The aspect ratio distorted the spheres and setting it back
to square made a major difference. I guess I will create an example but one
way to really see it is to render in a mode like 1024 x 10. Obviously the
spheres will be extremely warped due to the aspect ratio. 1024 x 768 isn't
as bad but is still warped. 1024 x 1024 gives the correct image. I'll try
posting an example tonight in the binaries.images section.
