ActionScript 3.0 :: Doors That Open Up To A Home Page Menu?

I'm having trouble creating code logic for 2 doors that open up to a business and personal section. I want them to be coded for all these scenarios:

1. when user's mouse is over the door (or section), the door opens up. the other stays put where it is. (done)

2. when the user exits the zone, the door closes shut (but slower than the opening)

3. if the user's mouse exits and reenters very quickly, i need to detect that somehow and rewind the easing function? example

if (user left and reentered in 2 sec){
trace(personalDoor.rewind());
}

what kind of method or class gives access to a rewind function.

[URL] put an http: before that and the whole link will work.
