LOOKS LIKE WE HAVE A WINNER!
The resolution picker worked perfectly, Scott. Thank you so much for saving my game. I know the resolution I need, so if updates resets things, it's an easy fix to get back to normal. BTW, I closed the resolution picker program and no change to the window. Also, I closed the window and when I reopened the game, it opened up to the resolution I had picked. Well done, buddy!
Your reputation proceeds you, when I first posted this issue, I was kinda hoping that you would see it.
