Carole, number the letters 1-8, from left to right. Then click on 5-4-3-8-7-6 and you should get a new message.
Now you can do me a favor--exactly what notes did you strike to solve the piano puzzle? Only one of us working on the game managed to get past it, and she sent the rest of us a saved game at that point. The problem is, she solved it by accident, and so none of us know the correct notes!!
