Roll over panel with buttons

Hi all,

Here’s my new puzzle. I can’t seem to figure it out. The idea is simple enough i think.
I have this button with an rollOver action on it that triggers another mc, this one i called panel. Now, what i want is to place a couple of buttons inside my panel mc. The problem is, i want this panel to close down on rollOut. I can´t just put an action on my panel clip since that would stop the buttons inside from beeing registered (as u can see in the attached file).

So, any ideas?

Cheers.
