While updating (to 8.4 or 8.6 or something), I saw a suggestion that I was supposed to remove "<meta http-equiv="X-UA-Compatible" content="IE=10" />" in order to make the client continue towork, but I do not know where to do this? I am hoping that this will take care of the script errors I am getting
