I'm heading back to the editing desk right now. Will check. But I even reinstalled VP18 and couldn't find the window. I saw some comments from way back in 2014 about this. Thank you all.
FIXED... My solution was to simply "X" every visible window from the screen and that left the Pan/Crop lurking from the shadows, formerly hidden from view. Moving things left and right would not show it. But X'ing everything did the trick. There it was! I thought that there might be some simple way to make it reappear. But I truly appreciate all of your thoughts on this. Back to work.....
