This is definitely a Mac problem as it work fine in windows.
I have a window with an HTMLviewer on it
In windows I usually call from some other place
helpviewer.HTMLViewer1.LoadURL("//www.youtube.com/embed/VogISB-8XWA")
and it loads and plays it.
It doesn’t happen on mac - I just get a blank HTMLviewer.
Any ideas? All of my help is videos, so you can see that this is a pretty big deal as I released my software 3 days ago and the first impression of my software is that the hep doesn’t work!
