Hello Peter, welcome to the forum! Please use English in the forum as most of our users do not understand Swedish. :)
To operate the rotational switches for radar mode and weapon selection, place the cursor over the switch and use the mouse wheel to rotate the switch. You cannot change the position of these switches by clicking on them in this version. This is intentional and not a bug, but we will probably bring back the possibility to click-select in the next update.
