It would be great if you could add an "X" icon or the word "Close" with an "X" next it so people don't need to place a call to IT in order to get by the message.
I just took a look at your site and there is an X there but it is hidden due to its color and the background. I think the support team would be able to assist here. I am creating a support case for you now and they should be in contact.
You won't be notified about changes to this idea.
