Commented out all channel and sound references (including the variables so I don't think I missed any) and it made no difference.
Quit all other programs but Blitz IDE and that makes no difference.
Could be a background app...but I doubt it. Note that dmaz is having the same problem. Plus, even if it was a background app that doesn't change anything - other than help track down what causes this. I don't have a screensaver on and judging by the short about of time the game runs before quitting, it doubt anything has time to activate.
