I have this problem with my Xbox Controller:
when I pressing the Z-Rotation "Button", the Z-Axis is activated too.
And then the Axis didn´t turn off.
In the Controller Settings from Microsoft, all is ok. And in other games the controller works too.
I checked it with my force 3d Pro joystick, and he works fine in arma.
S: Win10 #64bit
Controller: XboxOne Controller
Software Version : 10.0.10240.16384
UPDATE: tried other Controller Version and other Software, nothing helps.
