So something else to lay at Microsoft's feet, huh? I can go to my control panel and turn that sound off, but I don't want to tell all my users to do that. Don't suppose there is some Javascript that i could embed in the course to turn this off on a one-time basis? I want the click on the other buttons (i.e. navigation buttons) but I don't want it on these "play sound" buttons.Thanks,Mark
