If you are running GGE 2007 edition and you have VISTA operating system, the audio may not work properly or runtime error may occur. In this case downlaod and execute Screenshot pack #2, click on the Monk, then close the Screenshot pack #2 and restart the game.
All old editions of the game prior to 2010 don't work on Windows 7.
It might occur that some of the symbols/keys (required to unlock doors/puzzles during the game) cannot be selected or are just not available. This is NOT a glitch, but a protection that takes place if some of the information or objects required to unlock a door/puzzle have not been obtained yet. If all the information or objects have been correctly obtained, relevant symbols/key will appear as they should.
Screenshot packs
Two animated screenshot packs are available, although not yet operating on Windows 7.
