I have an external monitor plugged into my notebook, but I cannot move windows from the bottom screen (built-in screen) to the upper screen (external monitor).
The windows stick at the top border (below the panel) of the built-in screen, while the mouse moves into the second screen.
I think, it's because of the top panel; It works if I place the external monitor below the built-in screen.
How can I solve this issue? Or move windows directly without using drag and drop.
