Iparigrafika page flip . load external swf is ok, but

I´m trying to do something like this:

In certain pages, the user clicks in a button, to open a external swf. So far, so good.

But the page flip still active below the swf opened, and I have some problems with it. Why? Because the user can click in the corners and flip pages, with the external swf ( a mc with a picture) opened.

Any ideas? Can I “freeze” the page flip? Or disable button´s functions?

Example that I want to do:

www.jopatu.com.br

You click in a product, a page opens above the book, but the corners are disbaled.

Thanks!!

And sorry for my bad english…

[EDIT]

Found it!!!
