Layers and mc issue

I have a moveclip with a button over it. When you roll over the button a menu will pop up at the bottom allowing you to pause and start again another movieclip in the background.

Everything works fine except the way the menu presents itself–it’s conflicting with the button that allows it to display so when you rollover the menu items the menu wants to go away again because it’s off the button. Can someone take a look at this and see how the menu can stay on the stage for use?
