This is achieved in the installation script by: As such, I have created a seperate script (called 'Chessmaster Grandmaster Edition - Tutorial Patch') to restructure the tutorial directories so that all tutorials appear on the front pages of their respective sections. To work around this (at least until the issue is fixed in Wine), it is necessary to ensure that all tutorials are accessible from the front pages of their respective sections, so that users never need to use the navigation buttons. I have tested my scripts with Wine versions of 1.6.2, 1.7.45 and 1.9.0, and I have tested both the x86 and 圆4 architectures, but the buttons remain broken. However, most of these buttons are broken in Wine (see ). On Windows, the user browses Chessmaster's collections of tutorials by using navigation buttons. Chessmaster: Grandmaster Edition is the final installment of the Chessmaster series, which is the best-selling chess software in history.
