Serious Mac problem

Hi,

I recceived an email of a friend of mine that a site I made isn’t working on her Mac. Only the opening ‘film’ shows, but then the buttons don’t respond at all. I am shocked because the site is already online.

I load movies with a blank first frame, using loadMovie into different levels and then use

tellTarget(_level…)( gotoAndPlay(2);
gotoAndStop(levels …of all the other movies);

It works fine on pc’s.

Does anybody recognize this problem???
Are ther things you can’t do in Flash for a Mac?
Is there a tutorial about this?

Could you please check it and tell me if you have a Mac?
this is the link

thanks very much,
Jerryj.
