This issue was originally raised via forum thread: http://www.groupdocs.com/Community/forums/thread/18496.aspx
When annotating a document in Chrome and another Browser IE11 is collaborating on the same file, highlighting text to add a comment triggers an null reference error in the other client (IE11). This happens either way so this is not a browser-issue.
