Pause movieclip on click

Hi, i’m developing a small game using as3 , in that i want to pause my whole movieclip when a user click on quit button.

means when user will click on quit button , a dialog box will appear and will give options “yes” or “no”.

so when i will click on quit button , i need to pause my movieclip for the time until user will select yes or no.

And also , if he will select option “no”,application should be resume

i will try to explain wit hierarchy to understand my problem

On scene1, i have taken 3 movieclips on first frame but at different layers.

And Each of this movieclip contains minimum 5 children movieclips.

so i want pause scene 1 movieclip from 2nd or 3rd child movieclip.

so how can i pause that movieclip?
