Strange issue with blur function

i’ve created a movieclip that i’m applying a simple blur filter to and in Flash when i play the timeline it runs with no problems although when i publish the movie the blur doesn’t display - i’ve run out of ideas about why this could be! I’ve looked online and can’t find any suggestions either - does anyone know what i’m doing wrong?

I’ve included the .fla here www.chameleoni.com/example.zip

Thanks.
