I installed MegaPOV and it works.  No more disappearing sphere_sweeps!

About the use of spheres and cylinders...In theory, shouldn't a 
sphere_sweep using linear_sweep look exactly the same as spheres 
connected by cylinders?  If so, why doesn't POV-Ray break it up like 
that?  I'm finding that POV-Ray is shooting way more rays to test the 
sphere_sweep than is probably necessary...only 1-2% of the rays tested 
result in a success.  That certainly can't be efficient.
