Hello Benjy, thank you. Thank you also for your help.
Unfortunately, nothing happened. It was not on Aero to begin with. However, just to make doubly sure, I actually just switched to Aero and saw that it did fix the order in that first window opened was on the left side but it changed the view to thumbnails. So I changed it back to Classic and thumbnails are gone but the order is back to first window on top.
Any other thoughts?
