Import a swf - hidden buttons still active


I have a timeline with several buttons on it - some if these are created at runtime, and some by putting buttons on the page on frame 1

I then have an emptyMC into which I import a swf that COVERS the whole stage.

This all works fine - you can’t see anything of the underlying material. However, as you “mouse around” it seems that the buttons that are covered are still active - pointer becomes a hand etc. I can disable the buttons using enabled=false. This is quite invloved, and I would have thought that these buttons wouldn’t be active - surely they are covered!!!

How is the possible, and is there a neater way to stop these buttons being active.
