Can you tell me if the PGN export is run on their annotated games, then will the annotations be exported as well as the moves? And if the answer to that is yes, then do they have a CD-ROM or two that contains all the games -- annotated! -- that can be purchased? (But I am not interested if the annotations cannot be exported out of their proprietary format.) Dave
