[jQuery] Hide DIV on page click help

[Jeff]

I am trying to add some functionality to my page where a user clicks
on a link which makes a menu layer visible.  That part I've been able
to do.  Now, I would like that DIV to disappear when the user clicks
anwhere else on that page, on other words, making the menu disappear
when it loses focus.  Basically trying to emulate windows menu
functionality.  How do I make that happen?  Thanks in advance
