Internet Explorer Security Update Causes IE11 to Crash when an Instructor Accesses a Blackboard Learn Course

MSIE 11 will no longer be supported by JHU.  Microsoft ended active development for Internet Explorer in January 2016.  Over time, we have found more features of Learn no longer work properly with IE11 and Blackboard will not resolve issues specific to IE11. We recommend an alternate browser, e.g. Chrome, Edge, Firefox.

On February 11th, 2014, Microsoft released a Cumulative Security Update, MS14-010.  This security update causes Internet Explorer 11 to crash when an instructor accesses any Blackboard Learn course that has Edit Mode turned on.  This security update was pushed to all Windows users with IE11.  More information about the security update can be found here:

Please be assured that Blackboard is currently investigating this issue and developing patches to correct it.
