In every known Mac Version of Monkey Island I, there is
a bug problem on Monkey Island. This is Mac only because
of the different sound system.
When about to enter the Monkey Head, there is music
playing. WHen you enter the head, the knew music plays
but the old music from outside the head doesn't end. There
is no known way to turn either music off, except by going to
"silent" areas such as the beaches. However, when you go
to a "silent" place, the Under the Monkeyhead music
continues to play. Thankfully, it ends when you get to
LeCuck's Ghost Ship, (the Monkey Island Music plays alone
there, and it interferes only slightly with the other ship
sounds, such as the Ghost Band, etc.) Then, all is resolved
when you return to the Cannibal Village. You can test it out.
I have a save game right outside the Opened Monkey Head.
Good luck, and keep up the good work!!!
