O.k. very interesting. Please bear with me. Some things are hard to grasp without a connection to "above". He said it on Discord, I guess and the feedback is also from there?
Anyways. Although I'm using a workaround (mapping axes to buttons), I'm afraid that the problem will now remain forever for some(1 and me :D), since it has been solved for some others.
Btw: I'm using the analogue Stick of my TWCS Throttle. What about with you, guys?
