[RESOLVED] movie clip button animation fade in/out

[hobnob.bob]

I have web content with simple rollover animations. When someone rolls over the target a text box fades in. When they roll out it fades out.

How can I have a smooth transition if the user rolls out before the roll over animation ends (i.e. before it's faded all the way in) ?

See attached. "Receiver's Key" is the hit area
