Without a default track, people wouldn't know that it does music, so that option is out. A shorter loop is no good, as it gets too repetitive. I need a good 5-minute piece of music to avoid this. Looks like Door Number 3.
Cliff - except for one last-minute addition, I didn't choose the testers. But I do value your opinions. I'm sure your finger will be poised over the "M" key the first time MA3 starts
Oh, wait -- you've already pressed it, so you'll never have to do it again, unless I change the Registry locations. Or you could go directly into the Settings screen and turn off the music there before even starting the program.
