When starting the Linux demo, there is a "control panel" screen where I can set the sound and music volumes, etc. If I press the Start button to test the music, and then press the Play button while the music is still playing, the demo will crash almost instantly. At least on my computer it does.
Of course, a reasonable reply to this kind of bug report would be "don't do that, then!" As far as I can tell, the demo works perfectly if I start it while the music isn't playing. But I still figured you would want to know. :)
Good catch! We failed to test that set of actions. (We always pressed Stop before Play.) The demo has been updated with a fix.
