Movie Clip Hit state Problem

Hi

I have a movie clip for which I am listening for mouse out,over and click event inside that movie clip I HAVE another movieclip called tooltip for which I am not listening for any events

the code that i AM using to achieve that


tooltip.mouseEnabled = false;
tooltip.mouseChildren = false;

But for some reason its not stopping the event from firing and I get a very strage behaviour.

Please see the attached image file.

Thanks in advance for the help
