Button events not working

I have some button events like "on(rollOver)" that aren't executing at all. They're about 5 movie clips deep. As soon as I get 3 levels in, that is when it stops working. I can paste the button on the root level timeline or one level down from there and it works fine. However, any further deep than that and it stops working.

You can see the .fla here (though it is a pretty big download of 6 MB - I tried to take out the library elements that bulked up the size but the .fla didn't go down in size):

In that FLA, all of the menu elements that get expanded from the main menu should execute a trace command... but the events don't happen. This is frustrating the living HELL out of me. Any ideas??

hi,

This is what I can think of:
Make sure you have movie clips (not buttons or graphics)
Make sure none of the movie clips have on() events (and be carefull with any other code)applied to them (this would steal the events from the buttons)
