Also had this bug the last 3 times I played in a row, on 0.6 stable. Had a few times it worked again after a while but then later the bug occurs again. Experienced it with multiple rifles and pistols. Pressing the right mouse button with a raised weapon just zooms.

The issue is present for me in development build 0.8.0223. Invert vertical axis has no effect on rover forward/backward movement. (OS: Windows 7 64-bit; the joystick is Logitech WingMan Extreme Digital 3D if that makes any difference.)

I can confirm the issue being caused only when a joystick is connected to computer (Logitech WingMan Extreme Digital 3D in my case). Tested against development build 0.8.0223, on Windows 7 64-bit.

This is also the most missed feature without a doubt for me.
If you cant form groups (in game), the group channel is pretty useless, and spamming side channel is not an option for every little thing. Which result in less teamwork.

get this crash also occasionally, added rpt + dxdiag

I to had this twice, both cases I think since 0.74 (stable and dev).
Sound still works, screen is black, task manager says arma 3 not responding.
not after a few minutes but an hour or so ingame.

uploaded: dxdiag,rpt and bidmp

rpt:
DX11 error : CreateBuffer failed : DXGI_ERROR_DEVICE_REMOVED
DX11 - device removed - reason: DXGI_ERROR_DEVICE_HUNG

Thnx for the fix, really helped me out there.

Hope it gets fixed, because it was pretty confusing.
I double checked my controls 3 times to so what each helicopter control should be doing and then I noticed it was a bug.
