Smooth Rollover Animations

Ok, so i have buttons and when the viewer rolls over the button, a box slides out with content inside. When they roll out, the box slides away

So there are two animations, one for the rollover, one for the rollout

This is all great if they wait for the rollover animation to finish, however if they rollout half way thru the rollover anim, it jumps right to the rollout anim, and it isnt smooth

How do i make if they roll out half way thru the box just slides away from where it got to?

This is frustrating as hell :m:

Please help, i dont usually considder myself a noob at flash, but this is stupid i cant figure it out
