Level interaction problem

Hi!! Someone!! I have a movie that’s 500x400 px in level 0 and has lots of thumbnails with pictures that I want to open. the thumbnails open a 500x400 px movie above the other but on level 1. the problem is that when the new movie loads on level 1, the thumbnails on level 0 (that are now hidden by the new movie) are still active, and if i click anywere in the movie on level 1, it trigger an action from level 0. Is it possible to load a movie to level 1 that deactivates the movie in level 0 without unloading it??? please, please, please HELP MEEEEEEEEEEEE!!
