Tom,
I tried something earlier today. I clicked on my mouse at the left edge of the left monitor and dragged it as far to the right as possible. Lo and behold, there were my missing icons on a part of the screen that I could not see before the drag. I then dragged each of the missing icons as far left as I could and then dragged the screens to the left until I was back at my "main" screen. I was then able to reposition my "missing" icons.
Now that I have nothing on those extra screens, the four dots have also disappeared. I cannot drag my screen to the left or right any more.
My question is, how did those "extra" screens show up?
Ed
PS: Never did get to use that batch file.
