>I suspect a big catling bug by Fritz7
I think you are correct since many people have reported that
Fritz 7/7a has a severe castling bug. Buggy products, a bad winboard
adapter and now even buggy engines from ChessBase. Looks like they
just throw the stuff out on the market on fixed times - no matter
if the product is ready or not... And just you try to get support or
an answer from your complaints...The respect from Chessbase shown to
their customers is close to zero. If you are thinking of buying their
products be aware of what you are facing. There are a lot of alternatives.
For databasing Chess Assistent and the excellent free SCID. About support -
just compare ChessBase with the respones from Rebel/Ed Schröder,
Chess Tiger/Christophe Theron and Chessmaster/John Merlino.
