Some of our users are unable to launch a course in IE11 - the "circle of death" just spins and the course does not launch. However, others are able to launch the course in IE11. The course was authored in SL360 and published as HTML / Flash fallback. Will the problem for users unable to launch the course in IE11 be resolved if we republish as Flash / HTML fallback? Will there be any negative performance consequences to our other users who are not currently having problems launching the course? Thanks so much for your help!
