Well, it'll be a long time before I decide to use media again, if that says
anything. :-)

All Greek to me but I'll give it a whirl. Thanks so much for the
suggestions. I'm very, very happy to hear it might be an easy fix! :-)

The eye of this beholder is just abou frazzled, so I don't think it can
afford to be too picky. Unfortunately I know that the eyes of the beholders
that will be looking at this animation are going to be very critical indeed,
so I'm striving for perfection (and sometimes failing).

Yes, that's what it is. At that close of a camera angle it does appear
pixelated (I think my original image was 800x600). Too late to change now,
though - and I haven't gotten around to reading the part of the
documentation on sky spheres yet, so I don't know too much about layers and
all that. Eventually I'll get to it.

Thanks so much, Bob. You don't know how much frustration you've saved me. My
family thanks you, too. ;-)
