Movie Clip Problem...They Are Taking Over

I have my site which has buttons which play mc’s which open up to other mc’s which are different parts of the site.

A mc loads in then the buttons appear you click on the buttons and it plays a mc and goes to that section. And the button interface slides away. This is the same for each button. Now i have a button which stays on the screen at all the its like the back button. It i sment to play the original you could call intro mc and send you back to the interface.

On the button i have

on (press, release) {
tellTarget ("_root") {
gotoAndPlay(“nav_intro”);
}

Which works when you click it takes you to the start of everything.

This is where the problem starts, everything works fine you can press all the buttons all the mc’s play like they should. Then click the back button and everythign loads in again. However, once it has loaded in after pressing the back button i have no control over the navigation when you roll over a button it justs plays the mc without any clicking. Infact when you roll over any button it just plays button1 for examples mc.
Once you have clicked that back button you loose control over anything.

Anyone have any idea what this problem is, cuase if i cannot figure it out my whole site wont work :frowning:

Many Thanks for any help :slight_smile:
