You did it again Don!  That was the hint I needed - all because of RFC14, 
which I had recently re-wound.  Since I had re-installed that one part, I 
had thought it would be the last thing to create a problem.  Toroids. :-)

We're now on Part III of the alignment and assembling some mini-modules 
for the final push to testing.  Thanks very much!
