Unable to stop head tracking lockout with Tobii

[fullcoupe]

What does DCS look at to "detect" if head tracking is enabled/present? Also why is there no setting to toggle on/off in the launcher or in the in-game settings, like there is for VR users? 

I've been doing some missions that are switch- and MFD-heavy, and prefer to do them just using the traditional view controls. 

My tracker (Tobii 5) is disconnected, I've restarted my computer, even uninstalled the Tobii software. However each time I run DCS it seems to think the tracker is still in use, so my views are locked out. 

There is a "pause" hotkey option within the Tobii software but it simply stops the inputs; DCS still locks out the pan view keys (view down, view down slow etc) no matter what.
