.swf isn't displaying right under Mac OS

[Azek]

I uploaded my .swf movie at http://www.azekone.com/
It works fine under any version of Windows, but my friend who's running Mac OS claims he cannot see it. Any ideas why this is hapening? I don't have access to a Mac anymore, so I can't figure it out on my own :| Thanks.

Well, I guess my friend is to blame.
I asked a few other friends who are on Mac OS and they all claim it works fine. Turns out our friend here had forgotten to install the darn Flash plug-in for his browser. Doh!
