Hello Dr. Hyatt,
Thanks for the info.  I know that Fritz and other programs think that the
opponent has run out of time because of the "Lag" transmitting moves.  I'm sure
I can take your word for it that Crafty is not losing on time so my scores
stand.  I've been doing some test at Game/10 and a strange thing happened.  The
old Crafty 16.4T  from chessbase scored better than the Crafty 16.5 which is now
running with all of it's functions(Only 3/4 man tablebases).  The main
difference is that Crafty 16.4T used the Fritz opening book.  I think you have a
larger book than what I am using.  My Crafty book file is about 5.7 meg I think.
 I will look for a larger book at your site.
