Hi Judd, The OSG just adapts the windowing systems provided mouse xy values, and as such is limited to the clapping that happens due to the windowing systems. Getting the delta moyse xy isn't supported, and personaly I don't know how one would go about getting this extra info from the various window systems, I'm open to suggestsions.
