Help in optimizing my code

Hi there! I have this flash file I’d like you guys to check out. I based this from two tutorials from this site, mainly the infinite menu and the easing on mouse click tutorial. Now, I get the desired output for my flash but I’m not so happy on how it needs so much attention from the CPU. I’ve attached the fla file for your reference and I hope you could give me pointers on how to make the code more faster. Or is the code as optimized as it can get?
