How does Presenter/QM '13 know whether to launch HTML5 vs. Flash? Re: Microsoft Edge By Deborah Munitz So when you have a platform that runs both HTML 5 and Flash how do you know which one is actually running? When you hit a new course built with HTML5 turned on, on an ipad it runs. So this must be HTML5 because in the past nothing ran. Same for IE v11. Didn't run, now it runs. But on Microsoft Edge which supposedly supports Flash and not HTML5, nothing runs at all!! Why not? And on Firefox which supposedly works for Flash but not HTML5, how do I know what is running?
