this is really funny, my wifes name is barbara too. and the other day one of our doors (just) fell out of place. what seamed to be the problem was, that there is a plastic insert that goes into a hole in the bottom of the door, and after years of opening and closing this inset fell into the hollow of the door. it is for the adjustable screw that fits inside of it. if this has happened, and you can't get it out, don't worry, your local, mine is (TRUE VALUE HARDWARE) has replacements on hand. BUT, save the screw, because you might have to do some jury-riging. hope i helped.! GOOD LUCK.!
