Why we still use IE6 where I work, despite our constant talk about security

Here is what they told me at work when I asked about IE6:

"Internet Explorer (IE) has remained at version 6 while a conflict with the Customer Relationship Management (CRM) program was being worked. Because of this conflict, the (IT dept) did not deploy a newer version of IE. The CRM program was recently upgraded, and IT is testing to make sure that any such conflicts have been removed.Once we confirm this, IT will move forward with a site deployment of anewer version of IE. All users will be alerted when this deployment is scheduled."

Because some shit software that we bought and never fully implemented was not compatible with modern browsers? It's awesome.
