XML photogallery help needed

programming flash
1

Hi there,
could someone help me with this code.
Ive use kirupa’s thumbnail gallery and modified it a bit.
I,ve used troughout this site. www.mambocuracao.com/v2/index.html
Problem is that want to let the scrolling stop whenever i open a popup within the site. wright now it keeps scrolling and thereby people coulkd accidently open a other file while a screen is open.
i know how to use ._enabled but i can’t find the right function to stop it.
where’s my code… sorry i havent sorted it yet

import flash.filters.ColorMatrixFilter;
_global.myAgenda = this;
