I have one and only purpose for starting this thread. It is to correct a mistake that I made a little over half an hour ago. What was supposed to be a new thread ended up as a response to my own old thread! I have nothing to blame except for my own absent-mindedness! If anyone is interested in what I was thinking earlier in this sitting, he or she can simply read the response to my latest thread and pretend that it is its own post. I am sorry about that!
