It has been over 2 months, my problem has not been resolved and I have not
heard from anyone. Is this problem being investigated? Is there a problem
with PovRay? If PovRay is OK, what am I doing wrong? Would someone please
give me an update. It is frustrating waiting for answers and not knowing if
anything is being done to solve my problem.
