The xbox controller should work I assume you have another controller with a slightly hanging stick or so which produces input so it will always switch away from the xbox controller (maybe I should change this and let ppl klick x or so the confirm a controller instead of hopping to any kind of controller giving input). It is an assumption, bc I had a tester with a flight simulator hw setup which experienced the same.
For the settings, I asume you did not define all, so it you can not save. Also an assumption. I would need log files to confirm all of my assumptions (and thinking I should add something to the UI to make that easily accessible).
As soon I get access to my computer I’ll look into that.
