Apology happily accepted! Here are three screenshots. The first one is what I get when I open New Card, Screenshot-1 is what happens if I try to resize, and Screenshot 2 is from the "Guest" account on the same system, which it had not occured to me to try before. I wish I could show you the 'thin red line', but I haven't yet puzzled my way through the 'Help' on doing a screenshot from the keyboard!
