Hello: I have an annoying issue with my barometer.
Even after pressing the "B" key it doesn't set the correct setting,making the sims' ATC order me to contact various airports,centers etc...To check.

In the 727-100 captain I own if the controller tells me to set the pressure to 2956...I press the "b" key and it shows 2796; I've tries to use the mouse buttoms to set it,but it goes haywire,to say the least...

Can this be a sim issue related to FSUIPC,my sim installtion or the 727-100??? :-/
