Yes/No dialogs are always a bad idea — I’ve never seen one that couldn’t be better-written using different, clearer words for the buttons. Writing is a big part of UI design. My rule of thumb: assume the user won’t read anything other than the buttons. E.g., when you log out of Mac OS X, you get a confirmation dialog with two buttons: “Cancel” and “Log Out”. Crystal clear.
