Strange. Did you run Crafty in a dos box?

Well, I tried the

>>Nothing unusal. Then I tried adding the computer command.

After downloading the book.bin please create your *own* books.bin. Create a
start.pgn containing something like:

[Site ""]
e4 {play 5%}
[...]
[Site ""]
h4 {play 5%}

[Site ""]
e4 e5
[...]

as I posted before. After creating books.bin please terminate Crafty. Then start
it again. I'm sure the result of "sh b" will change.

[...]

Best wishes
