[CS3] hit test help please!

[teh shame]

hey, using as2, whenever i put a hitTest code in, such as

onClipEvent(enterFrame){
if(this.hitTest(_root.player)){
_root.player.gotoAndStop(4);
}
}

it works, just it hit tests if the player gets NEAR the object, without actually touching it..... Is there a way i can fix this please?

thanks in advance
