Windows 10 Taskbar Problem

[xxyzz]

I tried your suggestion and that did not work. If you hover your mouse over your open programs on the taskbar you get a small preview of each program that is open. If you click on any of them they go back to full screen except Hoster. The only thing that is on the screen is the floating display window. I though maybe the display settings were set up to extened mode but that is not the case.

When I tried your suggestion you get a preview of all your programs that are open just like above. When you click on Hoster is appears to open up for a fraction of a second then it disappears.
