Nested Event Handlers - Help!

I have a very large movie clip 2000px by 2000px that I allow to be dragged around the frame.

It contains within it a child movie clip that contains about 100 smaller clips, 8px by 8px, which are distributed around the parent. I need the child clips to have rollover funtions, and they should move with the parent when the parent is dragged.

It appears that these functions conflict. That is, I can do one or the other, but if I try to do both, the drag stops working.

Any ideas?
