Furzy,
I have a FF2 on win2k, and I get the same problem as you.
I also have a issue where the forces seem to change between flights, same plane, different force feed back, usually the elevator goes light.
Both of these issues have been since day one of FF introduction.
I guessed that the FF implementation is still not bug free.
Going out of and back into AH seems to clear any problems though.
Grayarea.
