I seemed to inadvertently stepped in that stuff Ted loves so much. And yes, I will accept the blame for whatever it is that I said or did to Mr. James A. Harrison. I will indeed "back-off" You do not need to ask twice. Eudora filters work great. By not seeing your questions or statements, I'll not be tempted to answer. And inadvertently do something wrong. I would, however, like to know why I'm doing this.
