This may be a computer hardware, or some software conflict issue, but for some
reason the example wineglass.pov does render the wineglass as "glass", instead
the surface of the glasses are all black, but there are white highlights from
light sources seen on the black surfaces. I just installed the latest version
3.7.0, on my laptop, loaded in wineglass.pov, and clicked on 'run'. I also run
the benchmark.pov, and all reflecting, transparent surfaces, and the sky, were
all black. I also noticed that the rendering time was very quick, less than 10
seconds. It was as if calculations for these surfaces were ignored.

So I installed Pov Ray on another laptop and everything works as should, that
is, wineglass.pov renders the 'glass' properly. Also benchmark.pov took about
3min to render and all the surfaces looked as they should.

So my question is: what hardware. or software conflict, issue would cause this
incorrect rendering behavior?
