[fixed] 2.2.6.1 right-click on selection (Pop/Ubuntu)

[broozar]

Hi everyone, I have the following issue with 2.2.6.1 on PopOS 20.04 (based on Ubuntu of the same version).

1. Start wings
2. Right-click in an empty space - select Cube (or anything else - menu works)
3. select a face
4. right click on face -> menu comes up, but I cannot select anything

Wherever I click, the menu just closes again. Highlighting an entry by moving the mouse over it does not work either. If I delete the cube, the "creation menu" (point 2.) is also broken.

So the right-click menu works exactly once.
