Hi, Ivan:<br /><br />Sorry, I missed you last night. I went to a barbeque party and didn't get home until late. I've added some comments&nbsp;and one one or two minor edits. Nothing critical.<br /><br />Two days I ago I went for a walk in mid-afternoon, in the heat. Not a good idea. I barely made it home. There's no fool like an old fool.<br /><br />Bye for now - George
