How can I make Y! Chess a menu item under games in my Y! toolbar? The only selectable game is Mah Jong why?

When I click on the games tab on the Yahoo! toolbar and select Board Games, the only selectable game is Mah Jong. Is there a way to add Yahoo! Chess to this list?|||im not sure why mah jong is the only thing pulling up, but i had a lot of trouble with yahoo chess in the past. eventually i switched over to playing on aol games free site. the chess server is much smoother and it doesn't seem to boot you half as often. its the best free chess ive found online. hope this helps!
