It is true, this 'trick' was necessary to get the GUI features like movelist navigation, variations, game analysis etc. working kind of reliable. (a) It is not horrible programming, it works the way it was intended, I just did not realize it would break crafty. Problem is the winboard interface was never intended as a computer interface and has it's short comings, not to mention the variations amongst engines. Anyway, the winboard adapter is being worked on and this problem will be fixed soon. Lex
