I am running both programs in their own directories, including a ..\book\ folder
off of each. The versions of books.bin & book.bin were downloaded from the
Crafty FTP site as of 1-25-06 (didn't build any custom books). The strange part
is, after repeating (50x) the game I mentioned above, it somehow broke free of
this pattern and started up on unique games again during the same match. Also
as Peter Skinner mentioned in his post reply, I do have bookc.bin in each folder
as well and I am using the "Computer" command in crafty.rc.
