Not for me.  It no longer segfaults.  But now a window pops up containing a
yellow sphere, and a split second later the sphere is replaced by yellow
garbage.  The window responds to rotation mouse gestures, but not zooms.

Point of interest #1:  the original code worked fine under WinXP.
Point of interest #2:  it was not necessary to declare scene.range in WinXP.
Something else:  I don't know which version of visual I was using when I was
using WinXP.

Bruce, if I'm not mistaken you are relocating, and therefore probably very
busy.  But whenever it's comfortable, I'd appreciate it if you can try my
code on your home-grown build, and, if you still have it available, your
from-Ubuntu-repository build in order to see if it works on one but not on
the other.  If it does, any pointers on building on Ubuntu would  be
appreciated.

Thanks very much,
