Okay Pete, thank you.
Why I was thinking of FSUIPC as the problem, is that it is the only thing different between my two sim setups. And it do take care of communication between P3D and Prosim, doesn't it? (I ment the jan 9th version of FSUIPC, by the way)
My thought was that it doesn't care for Prosim which sim is in the other end. But I have been wrong before :)
But I do actually have a problem with FSUIPC in P3D, and that is calibrating my controls. They work flawlessly in FS9, but when I switch sim and FSUIPC version, they are very difficult to calibrate. Both Steering tiller and Ailerons will not center correctly. I have to hold them to the right of center to set the centerpoint for the centerpoint to be right when they are in center. Did that make sence?
Best regards
Rune
