Problem solved today.  I learned that the problem definitely started right after our annual Christmas Play-there is a lot of activity that takes place in attic where the projector is plugged in at that time-so I went looking thinking the projector had been plugged in to a different circuit.  What I found was a temporary strand of lights that had been plugged in to the projector circuit-and apparently left on 24/7 since then.  I did not take time to verify, but I suspect the real culprit was the fact that there were a number of CFLs in that temporary strand (and more than likely a stay neutral/ground bond as well).  The projector is scheduled to be moved soon-at that time I am thinking a dedicated single receptacle-perhaps even a TL to discourage tampering!
