The shout box is fine. It is the tweet box. The tweet website is one of those blocked/restricted/unapproved sites for the Federal Government (it would do the same if it was facebook). As we block the site, a message comes up stating the we are being rerouted to a secure site (our own) and the popup window stating this shows up in the way when trying to go back to previous views without allowing the change to the previous view. A quick double click on the back button allows you to jump past the popup warning.

Note: This is not a problem with your site but our site blocking system.

Thanks for the concern.
