[jQuery] Retrieving the location of the mouse click within the browser window

[Kalpers]

I am trying to retrieve the location of the mouse click within the
browser window.  When a user clicks on an area that they thought was
click-able but is not I want to record that location.  There is a
similar application already out there called heat click but I would
like to create something more simpler in JQuery.  I only need to add
this to a couple of pages to see where there may be some issues with
the layout of the web page.  Right now I am using the following code
but it it returning the offset of the element which makes perfect
sense.

$(document).ready(function(){

            $("#Form2").click(function() {

                      var loc = $(this).offset();

                      alert(loc.left + " - " + loc.top);
            });
        });

This always returns 0 - 0 which is the offset of the Form2.

Thanks
