     Combined script for tracking external links, file downloads and mailto links
     
     All scripts presented have been tested and validated by the author and are believed to be correct
     as of the date of publication or posting. The Google Analytics software on which they depend is 
     subject to change, however; and therefore no warranty is expressed or implied that they will
     work as described in the future. Always check the most current Google Analytics documentation.

     Thanks to Nick Mikailovski (Google) for intitial discussions & Holger Tempel from webalytics.de
     for pointing out the original flaw of doing this in IE.

While the exact number is different depending on the source, most believe that after a visitor is on the site longer than six to ten seconds they are no longer a bounce even if they never click to another page. This function adds an event for people who are on the site for more than twenty seconds (being conservative), so they don't show up as a bounce.
