transition tween stops tweening when cursor is over nested MC's

how's that for a long thread title...

Anyways, I'm making a drop down menu where the entire menu is in one movieclip and when you hover over it it tweens down to reveal the menu contents and when you hover off of it it winds back up.
Inside that container movieclip that tweens, there are several other movieclips that I was going to use as buttons.

The problem is when you hover over the container it scrolls down but as soon as the cursor hits one of the nested movieclips the MOUSE_OUT function gets called and the container moves back up.

I was wondering if there's any relatively simple work around for this, if it gets to be too much of a pain in the butt I'll just make this menu another way.

Here's what I have so far if my explanation wasn't clear:
