I am trying to focus and blur a flash file because I am using the scrollwheel in there... But the blur does not work.. even when I try to set focus to a different element or trigger a click. Does anybody know a good solution for this?

Code:
$(document).ready(function() {
    $('#ebookContainer').hover(
      function () {
        this.onmousewheel = function(){            
            return false
        };
        $('#ebook').focus();
      },
      function () {
        this.onmousewheel = function() {            
            return true;
        }
        $('#ebook').blur();
      }
    );
});
