I'm trying to make sure that any currently playing sound is immediately terminated if a user clicks on a standalone app's close button under Windows NT. I have put handlers for "CloseStackRequest" and "CloseStack", both of which do "play stop". However, some of the time it works and other times it doesn't! It seems to be more likely to fail when my app is running as a standalone rather than as a stack with the MC engine running as a Player. This is with MC2.3.2b4 by the way.
