Bob, At first I thought I may not be insane after all. But now I think the
two of us are ready for the nut house. Just out of interest what is your air
temperature and humidity? I think these are no longer the cause of the
problem but I need to check anyway. Out of interest I found another strange
reaction. Try this- Put a thick wire from the base of the secondary, (which
is earthed) along the floor, up the wall, over the roof and dangle it about
1ft over your coil to attract some arcs. My arcs ignored this earth but
attacked me instead, beyond the distance they normally travel. I know I
shouldn't get too close but made the wrong assumption that the earth wire
would give me some safety by keeping the arcs occupied. I can only get arcs
in air conditioned areas.

This is probably a stupid question but is it possible that the wire
connected to the base of the secondary is acting like a secondary antenna on
its own? Then it would have an output similar to the real secondary and not
attract the arcs, leaving the arcs free to get me.
