I just discovered this neat PGN database/viewer program, but on "Help | Help Topics" I get: "404 - File or directory not found." I've emailed the author at the Help | Contact address, but meanwhile poking around the other menus seems quite helpful and fairly intuitive. Hope it's still active - the last update was in February 2012.
See also their positional chess database PosBase.
I downloaded Chess Pad 2. Does anyone know of a manual or a website that explains how to use the program?
