Rewind Button

Hello, I have been playing around with the usage Rewind feature in Flash 8,
To illustrate an example, instead of a button, I have a movie clip that plays on mouse over and on mouse-out it rewinds. It works great BUT here is the problem

I create Button and as the user hovers their mouse over, more buttons falls down (thats the problem, it will fall down and rewind on mouse-out but the buttons act all as one button, I want them to be clickable individually). Here is an example of what I mean:

example:

How do I make the sub-buttons that fall under clickable rather than it act as a whole one button. please help:nat::cantlook:
