views_megarow.js correction

 // Bind a click for closing the megarow.
  57     $('.close', megarow).bind('click', { entityId: entityId }, function(event) {
  58       Drupal.ViewsMegarow.close(event.data.entityId);
  59     });
  60   };

Change the above line to this one. This will prevent the the browser to scroll to the top while clicking the CROSS link.

 // Bind a click for closing the megarow.
  57     $('.close', megarow).bind('click', { entityId: entityId }, function(event) {
  58         event.preventDefault();
  59       Drupal.ViewsMegarow.close(event.data.entityId);
  60     });
  61   };
