    1. I hoppe I didn’t steal any of your thunder: I feel, like you do, that there is ALWAYS a cause and usually it can be determined, but if it CAN’T be identified, it isn’t right to call it IDIOPATHIC. My comment was solely based on what I’ve chosen to do with my ON which has many potential causes.
