WOS: Holding Ctrl and clicking with the mouse doesn't work

You tried to change the destination display, but holding ctrl and clicking with the mouse doesn't work? 
Please ensure your mouse is mapped on the right keys. Go to > Options and then > Controls
The left and right keys of your mouse should be mapped correctly, if not, please go to line "Mouse function button" 
and click two times in the right field.

Now it should work!
