That was what Per-Ola meant and I am clarifyng for you, just in case. I am fairly sure that you should have understood the modest statement by Per-Ola _fairly well_. Now that we are through with semantics, I wish you a nice weekend. Although it is the end of November in Europe the weather is spring-like; I just hope it's half that nice in the USA...:-) Regards, Djordje
