Disable menu

Hi everybody,

I was wondering if someone can help me with the following question.
If you look at http://adobe.cover05.nl/special/popup.php? you see a little help button in the bottom right. When you click the button the whole screen gets darker and some functions get explained. The main question is, how do they make it possible that all the other buttons are not clickable nomore when the help function is active.

It would be nice to have a tutorial for this or some other good info.

Thansk in advance.

Regards,
vectar
