Ok, this may take some finagling, but none of these options were working for me. I brough up the displays, with both of them hooked up, and started moving the orientation around unitl the top of the window popped back up. Basically rearranging the display locations in regards to each other in the settings on this screen. Worked right away. I lost the top on the middle screen, so I dragged the middle screen up and was able to access that area.
