Cascade UI Bug

I just worked in cascade and were changing the Toolbar from the top the the right side. Now the Toolbar is on the whole screen and all I see is the toolbar. I tried to reset the layout, but this didn’t worked. The view is bugged in every project now. How can I reset it?

I fixed it. Had to plug in my TV, so I could drag the cascade window over my screen and the TV. Then I could reach the tap for the toolbar and changed it back to the top.
