If you've never played the original Myst, his post might not make sense.
To the OP:
When does this happen? When you press the keys on the piano?
Keep in mind, Myst is an old game. The "updated" version that was supposed to run on Windows XP is finicky and still has problems.
You need to set compatibility for Windows 98 or Windows XP since you're running Vista. Try that and see if it fixes both issues, this one and the one you posted in the other thread.
I tried to play the new version designed for XP on an XP machine and always had problems. Never could get off the first island because of it.
