Maybe you can give me some >other positions that are not retrieved, so we can try and duplicate the error. Gunther explained the problem very accurately in his post. I can add that if you a) set up a position, i.e. the Pillsbury one b) right click on the board - you get the option "search in...Big2001". Now, this search will also result in nothing, obviously for the same reason mentioned by Gunther. This is not good. Sune
