Jaba, I hope you get some answers soon. It's so frustrating when you know something isn't right and cannot get an explanation. And I'm with you on a single level house. We've got a two story on a basement and my sewing room is in the basement. It seems some days I go up and down dozens of times and my old knees are definitely starting to rebel against it. I'd like to move to a ranch! One day, maybe.
Terriamn and Jaba, yes, classic blocks are some of my favorites!
