Unable to traverse/elevate turret while firing coax

[migmadmarine]

I've had this issue since the first release of the tank crew vehicles, when I hold down RMB to fire the coax machine gun, I am unable to move my point of aim until I cease fire. Is there some keybind conflict I am overlooking that I might have RMB assigned to that would prevent me moving the turret? I've looked several times, but can't seem to find one if there is.
