Hi LOF_Rugg,
...See that's the problem with the TrackIr, it's not even listed in the DCS controls GUI. I think that is because since I updated to DCS 1.5 I have not used TrackIr in the game so DCS did not automatically detect it and list it in the controls GUI...
It'll detect it, if you turn it on and, then, start the sim. Dumb question. Are you scrolling the input screen to make sure TIR isn't hidden to the right? I ask because the first time I used 1.5, I thought I was missing something and discovered it, when I noticed the scroll bar.
