Hmm. Don't know how I missed the need to clear the content of the renderer. Until I add such a method, you'll have to clear the renderer by hand... protected function ...

protected function reset(event:MouseEvent):void
{
emitter.killAllParticles();
renderer.bitmapData.fillRect( emitter.bitmapData.rect, 0 );
}

...
