I use a Saitek X-65f for my hotas. On this image you can see the button marked T4 as my center button.

In previous versions of Trackir it shows up as button 45. The latest update it no longer works. I can't map it in the software and my profiles with it used as the center no longer work. None of the buttons on that part of tge hotas no longer register. Normal hotas buttons work.
Would be nice to have it back as is very convenient to use, within reach while not using up an actual hotas button in a sim.
Thank you
