Dave; It would appear that you are intent on hounding me away from this forum for whatever reason so so be it. I have never asked for nor expected patience from anyone here so if that is what has been shown to me then I would like to than everyone for their forbearance with my ignorance. Oh, by the way, last time I looked I wasn't a troll. As I said, I have enjoyed the threads that I have read here but if you don't want me to participate then all that you need to do is say so. Calling me names is pretty childish really- but whatever floats your boat is your business I suppose. The moderators can remove me from the list if that would make you feel better Dave. Ciao DGM
