Problem with gallery AS3

hi,

I’ve created a website and I’ve inserted in one of them a gallery in AS3. It works but I’ve a very big big problem.

After visited the page with the gallery, the gallery remains always on the background, I mean if I’m visiting the gallery with all the photos (in the “image” page) and then I want to back to the “home” or to another page, the gallery is still on the back, so I’ve the normal home with the text plus the gallery on the back.
How can I fix it?! I want that when I click somewhere else it disappears…

Thanks for your advices.
Here’s the code:
