Floating object in a confined area

Okay I have a 3d logo in a flash movie that is 350 wide 91 high. I want the logo to only float around in a small area way on the left side of the movie. Also stop when moused over. Basically I do not want it to float all around the movie just in its region and very subtly or slowly so it is not annoying.

Can anyone please help me?

ANy help greatly appreciated

anything out side of 3d and photoshop I suck at especially AS but I am learning slowly


ok I can take a hint
