Multi-Level hitTest destroying _globals! Help!

My dropdown menu contains a hitTest MC that unfolds a section containing another hitTest MC. Buttons in the second level hitTest loose their _globals and I have no clue why. There is some conflict between the hitTests and the _globals.

Example: http://www.earph.com/test.html

The “main” button should stay on when you touch “button 3”, like it does when you touch “button 2”.

Does anyone have a clue to what’s wrong, or possibly know a better way to pull this off?

I appeciate it!
