I do a menu frame under my web site and it work good under PC but under MAC there is no menu on screen, I think it's a bad configuration of the menu.
I copy the text of the frame_header_arrays.js,
I think it's the problem, but where

Thanks a lot, and congratulation to the Menu's people
Here is my code:
