No problem.  I had forgoten that I used to load positions into Amy in it's Dos
box instead of by using Winboard, and I think that works better.

The minor trick to pasting them into the Dos box is you have to enter "epd "
first and then paste it in with that clipboard icon at the top of the Dos box,
and then "analyze".  Works like a charm, and makes it's own log file.
