This is something I am going to file away in my memory for later. Good advice. Worth a try. This model, though, already is smooth. I'd have to figure out how to modify it and try all over. I just want to say how appreciative I am that you guys would try to help me get to the bottom of this. And it sounds like I'm not all alone either, so that actually makes me feel a bit better. I'm going to keep working on it.
