Unfortunately this new version does not completely fix the issue. Yes, the pitch oscillations are gone, but apart from that it seems that the changes within XPUIPC have affected some other commands. In my install e.g. I use Trim assigned to my joystick's buttons. Trim up currently is not working as designed anymore. At each keypress the sim is temporarily (for the length of the keypess) paused and the trim moves only a fraction. Reinstalling the former version of XPUIPC makes the buttons working as before, however of coure brings also back the pitch oscillations.So I'm still hoping for a better fix.
