With Firefox we can observe the default action when dragging the mouse (the left mouse button is pressed and the mouse is moving). During this default action the semitransparent picture of the client web page is displayed above the scroll button or over places where the dragging is happened. It affects dragging the scroll button because the transparent web page picture is displayed over it. To test these effects please set breakpoints at this function listener (p2j.screen.js)

      function mouseDragOverHandler(evt)
      {
         evt.preventDefault();

         // limit the actions allowed
         evt.dataTransfer.dropEffect = "move";

         return false;
      }
