title: Scroll view does not respond
body: <p>Works great for portrait mode. If I go on landscape mode I have my activity drawn in the center of screen which leaves blank screen on both left and right side.
  If I drag by keeping mouse on views (i.e. center)the scroll takes effect.
  If I drag on empty right side no scrolling ? why ?</p>
