It seems that when I try to sit back I end up behind the seat.
I you have settle into your comfy position, press F12 to reset the camera and viewpoint and then you won't be behind a seat. ;)

I agree with Otto. Buy the Track Clip Pro. It really is well worth it.

@ CoolP. I use the EZdokCA setting at first, then I went and tweaked it. It is not so sensitive any more. It really neat. I'm really not sure exactly how EZCA and TrackIR work together, but it sure works nicely.

The most unfortunate thing for me, at the moment, is that I'm stuck using the Track Hat and Track Clip until I get a new set of headphones. :(
