If you set a group to have background behavior then it sits above the 
stack layer in the message path (or below, depending on how you view the 
layers). At any rate, messages will hit the background group before the 
stack script sees them. That's the way it is, the way it has always 
been, and the way the path was designed from the start. If you want 
something different you need to rethink your stack design.
