i own 3 Microsoft FF2, hands down, i cant fly with another stick, so i got 2 other spare sticks for the next 20 years
ok, got the same Problem, but i got also a workaround!
Sometimes you start ah, all fine, sometimes you loose just X of Y Force!??! what now?
My Workaround-> open pref -> open forcefeedback -> DISABLE the overall FF checkmark and click Apply!
close this subwindow, open it again and checkmark Forcefeedback and click ok!!
Voila, all forces back up, stick works fine!
