jquery after php include

jquery after php include

Hi,
 
First off all, JQuery is great! :D
 
I use jquery to navigate through menus and load the related pages into a target div.
 
So, onclick of the menu, is calling a php to do an include of the html page that I want. Inside that included html, it has some more jquery functions related to images and so on... 
 
Everything is good with IE7/8 and Chrome but with Firefox, the jquery functions are not working...
 
I've made a test page for you to help (pleeeeaaase):
 
 
With IE7/8 and chrome, if you click "Menu1", it will show somekind of pool. If you move the mouse over that image it will show a larger one, right?
 
With firefox, that image won't show...
 
That image is controled with this plugin!
 
Hope you can help me!
 
P.S.: if you need, i can post the code!
