One mc on, the other off

I have a navigation system, that has a bunch of buttons.

When you rollover a button a movie clip fades in, and when you rollout the movie clip fades out.

My question is…

how do i make sure that when you roll off of one button the movie clip fades out…and doesn’t stay…because that happens somtimes…

i have posted my .fla so you guys know what i’m talking about.

For that type of effect, I usually use the hittest function.
While the hittest is true, it goes forward, when false play it backwards.

I think the problem in your fla is that there is a stop on frame 4 of your animations, you are rolling off the button before it hits frame 4, maybe your button’s should be gotoandplay(4) instead of just play.

thanks!
