Peter - Michael,

 I appreciate you coming to the rescue. It seems I am to be forever plagued
by this bounding box issue. I had no idea that one of the earliest pov object
types did not have an internal bounding scheme. I can see where it would be
a mother of a project to make it work. I will try to pound this into my head
with a large blunt object concerning this issue of bounding. For me it has
become the single greatest contributor to overly long gathering times and
twice now it has tricked me this way. It wont happen again I can assure you.
