Last night before I went to bed, I found an epd with a crouded board from Dann's
Deepmates.epd, and I was going to let Comet crunch on that while I slept, so I
thought I opened the log file and deleted the contents, and rebooted into Dos to
run that.  But when I got to Dos I found that I deleted the contents of the epd
file instead of the log.  So instead of going back to Windows and fixing the
problem, I got the Nunntest from a different computer and ran Comet on #10 for a
few hours.  On this one it went negative for a while, and then it went positive
after that.  Hmmmm...
