Problem with the Bush Whacker Game I made

Some people noticed that it was possible to get over 1000 on this game I created. That happens because people click too fast on the Bushes and the scoring can't keep up when a Bush is toggled before it stops moving.

I have tried to disable all the movie clicks until they finish playing, but the computer remembers where the clicks are even when it's disabled, so that they are affected in the same way anyway.

I have tried everything I could think of to fix this problem. Everything I have tried so far has failed.

If anyone wants to look at this Flash MX 2004 file (named Bush_mole_score.fla), they can download it by clicking here.

I'll offer a $5 prize through Paypal for the first person to show me how to fix this correctly, to make it a little interesting. Go for it now before I find it myself and rescind the offer.

Enjoy :)
