Button Movement

Hey all,

I was running thru the forums and tutes today and i was looking at the random movement (vibration) effect.

I thought this would be a kool effect to have on a button, IE when the user runs their mouse over the button it starts to shake. But i cant get it to work…

Anyone got any ideas?

Ive got the movement effect to work on just a simple movie clip, but not within a button. It seems that as soon as I put it in a button the movement stops working…

Any ideas would be greatly appreciated.
Thanks
