Buttons in a draggable mc

I’ve got a draggable movie, a timeline with a lot of entries. I want to be able to click on the entries to have an enlarged callout appear. But when the buttons are inside the draggable mc, the startDrag onPress overrides the buttons. I’ve now got the buttons in a mc on a separate layer and I want to have the buttons mc move with the draggable mc so the buttons stay in the proper location. No luck so far though. Any help will be appreciated!
