Issue with movie clip getting stuck if mouse goes over button before animation finish

Hello,

I am curious to know if it is possible to fix this issue I am having. I have 4 flyout buttons on my flash and when you RollOut of the button, it plays the closing animation. But if you quickly move the mouse back onto the button before it is finished playing the RollOut, then it gets stuck and flashes and kind of strobes.

Try doing that in the flash I have attached. You’ll see what I mean. Is there a way to fix this?

Thanks,
Lorne
