Hmm, yes. The problem is obvious. Can somebody explain what units
lyxrc.wheel_jump is supposed to be in, and I can fix it ?

    420         double const diff = t->defaultHeight()
    421                 + double(time) * double(time) * 0.125;
    422
    423         scrollDocView(int(diff));

should be something like

        float add_value =  float(workarea_.height()) * float(time) / 100;

but that was disabled in the old code. Somebody help please !

thanks
john
