Yep, it works properly now after the update, I was struggling with it for quite a while, it would work for one mission then if you exited the mission, it didn't work, you had to stop and start the facetracknoir app to get it working again, it was the only sim that did it, none of the others did, but now it works every-time no problems at all, so far anyway.
So yes I had issues with it on the Sabre only but now they are gone.
Edit: I did dump the headtracker.dll file into the DCS folder, cant remember the exact name of the file or the exact location, just google it.
