Movieclip timeline control problem?!

HI, I am a newbie in flash. I have a problem with the actionscript that I use in the FLA I attach below.

The main point is I make several movie clip as buttons. If one of the buttons is clicked, the set of the buttons will roll until the selected button is located on top. But, the problems are:
[]The movie clip is always in play position. Even from the beginning. How to make it stop but still functioning? (I try to stop them but it is not functioning.)
]The movieclip is blinking. What make it like that? What is the problem?[/LIST]
