onRollOut function / button state sticking

I have an issue that has been plagueing me all morning. I’ve searched and searched on google, here, other flash help sites, and even though I’ve seen a couple people with related problems, no solutions have seemed to tailor to my project.

I am working with a series of invisible buttons that perform actions on a movie clip and a text field to simulate the rollover. However, I’m finding there is a problem with the rollout. When you move your mouse over the buttons quickly, they often seem to ignore the rollout command and stay on the rollover state.

Warning to anyone downloading the zip is that I’m utilizing mc_tween. However, I created this same scenario a couple weeks ago (lost my work from a faulty drive, and I’m redoing it now), and I had no issues. Obviously, my code ended up slightly different in the rebuilding of this thing, but this side effect is really holding me back.

If anybody has any suggestions, that’d be wonderful. Thanks.
