It looks like the ZoomPanel does not receives the mouse events.
This can be caused by having focus on some other element. Try calling Focus on the ZoomPanel.
If you would like to use mouse wheel also when the mouse is not exactly over the shown object but is on its background (let's say a little bit right of the tiger's head), you can set the Background property of the "tiger's" parent element to White or Transparent - having it to null will not send mouse event to this elements. But if it is Transparent (or White, etc.) the mouse events will be send to this element also.
