Error loading pages in an organization

I have a user that is getting the following error from CRM 2011 IE 9.0. The initial page loads fine however when she tries to click on any other entity she gets an error message. Below is the description from the CRM Error Report.
Have any of you come across this issue before? I can access the same organization with the same rights as this user and do not get this error.
