maybe hitting the ESC key breaks the loop and shuts down the error. Resetting the stick/usb port most likely would restart the continual firering again. I'd think if after hitting the ESC key, if he unplugged and replugged the stick....as long as it USB if it would reset and be messed up again.
Then again, if its NOT a USB, I don't know why hitting ESC would reset the loop in a sound card. hmmmm interesting
