Weel Rosebud, upon further scrutiny, we are both right. I started the a thread but the website combined it with the thread of r. simes which basically asked the same question. When I have come to the thread, it goes immeidatly to my first question. In any event everything that came after my question was either non responsive or not understandable. I don't know if most of the people using the website have lots of time to waste; but, assuming they don't I just think this website if more effective and efficient if people stick to the topic and communicate in a manner which can be understood. But then, what do I know, I am frequently wrong about things.
