Story.html embedded in a web page - IE9, HTML5 issues By Glenn Simsek We have a course that is embedded in a web page. This works fine for Chrome, Firefox, IE11 and Windows Edge. When the user tries to launch the course, a few issues can occur: The course does not open in IE9; the user sees a blank screen. The course does not open in iOS devices. My guess is that the story.html does not run the "sniffer" when it is embedded in another web page. Has anyone else had this problem and found a solution?
