You guys were right. After three hours, the problem seems to have gone away. Even though it showed me as signed in, I think it was signing in again to respond to your comments that may have done the trick. All I know is, it looks good now, and I need to step away from the computer for an hour or two. Hopefully, it will let me post this afternoon.
Big Hugs to you guys for your encouragement. To quote another famous line, “Ah’ll be baahck.”
