"focusout" jQuery event I am using Drupal 6 and, therefore, jQuery 1.2.6. 

When a user clicks inside my text, there is a pop-up that comes up with a few more options in it. I would like this pop up to disappear when the focus is moved to anywhere outside.   This answer on SO comes very close but the focusout event isn't available to me in jQuery 1.2.6.

Has anyone else encountered this issue? How did you work around it?
I would rather not use the jquery update module, as I don't own the site and don't want to be responsible if the update breaks something else.
Add a .mouseleave() event to the popup div

Taking the example code from the SO question you mentioned, see the working version at http://jsfiddle.net/Laxman13/Mw8VD/6/
