Drop Down menu problems

I've created a few seperate buttons from which each of them when rolled over play the menu movie for that specific button. within the mc i have buttons which will play mc's on the root, which work fine. My problem is I have it set, so when you rollout of the main button(which plays the menu mc) the menu will dissapear. This works fine for going back and forth from button to button, but i want to go up and try to select a sub selection in the menu mc it dissapears because of the rollout action. So i then put an invisible button in the menu mc to play that movie while trying to select sub menu buttons. This keeps the menu mc up, but the sub menu buttons go insane and flicker. Causing it to not work. I"ll throw up my .fla, hopefully someone can point me in the right direction.

I downloaded your fla but what you are saying is happening and the fla do not corrilate. Am I missing something?
