Took the JS out of Drupal Behaviors The way the JS was written before was making the system slow. I reworked some of the JS so that it is faster and fixed a few conflicts with Colorbox. I discovered that having the ifrome mode off caused the colorbox call to be hit multiple times. With the ifrome option on, the browser referrer is set to the site and is not hit again. I'm going to remove this option from the admin.
