As we now, u cant have multiple onRollOver-onRollOut on nested MovieClips becouse they comflict each other, and the use of the hitTest is very unpredictible 
and give some surprising results 
This apply also for behavoirs as buttons inside of MovieClips.
So here is a prototype to manage this problem(Flash MX).
If u find a better code/way, or can improve this code I want to know. Also if somebody translate to AS2, please post the result.
