A security update recently pushed to all Windows users who use Internet Explorer 11 causes the IE browser to immediately crash when accessing a course with Edit Mode turned "On". Blackboard is aware of the issue, and while a long-term fix is promised from Blackboard Support, we have a potential workaround which we can implement on our Blackboard system which alleviates this specific issue.
This problem only affects Internet Explorer version 11 which have Cumulative Security Update MS14-010 installed. Safari, Firefox, Chrome and earlier versions of Internet Explorer are not affected.
We'll update you with new information and confirmation of the maintenance window.
