3D Display Object Interactivity

I’m having trouble retaining interactivity in a DisplayObject (MovieClip) that has been altered to become a 3D object in Flash 10.

The current structure is as follows:

MovieClip1 with Mouse EventListeners nested inside MovieClip2 inside MovieClip3.

MovieClip3 is rotated in 3D space via rotationX and rotationY as well as in Z space. After this happens interactivity in MovieClip1 does not function. Any ideas as to what I need to be doing or not doing? Thanks in advance.
