how do I enable TrackIR in latest version of TS?

That's fixed it, pressing F12 to center it did the trick no other fiddling needed. In the short time I've tried it just now, it was amazing I don't know why I did not get this any earlier during my Flight Simming days.

I've just bought TrackIR5 with just the baseball hat clip - I didn't need the track-clip pro for headphones.
I'm very impressed! it really does give a new dimension to the simulation.
I can now look at the scenery, passing trains, look back at the platform with my head out with ease

One thing I did find, if you have light pollution behind you it does goes bezerk. you can change the settings but I was sat behind a window with no blinds with the sun blazing in. Now it's dark and I have lights on in the room and it's fine

As a long time TrakIR user I have one of the original baseball caps they supplied with the TrackIR
