Please, post this message in this forum

People will help you promptly.
What you have to do is to run this in "Debug" mode in winboard.
It is just a switch in the command line but unfortunately I do not remember it
now and www.tim-mann.org is down right now. I think it is -debug or -windebug
or something in from of the command line.
That will generate a file winboard.debug that has all the details of the
communication between winboard and crafty. Please, post this problem in
the forum I gave the address because it is important.

Regards,
Miguel
