JR, after reading your post I turned down the realism settings to mid point and then the rocking issue went away. I am almost sure it has to do with the General <slider> in the realism options. Thanks for the input. Although it is still a problem because I use the program with full realsim settings and anything less would not be a real flightsim. I never had this problem with any of the MS aircraft nor any addons that I have tried. Well, atleast the people @ captain sim now know the cause of the problem and can help me resolve the issue.
