Well, the behavior I see is very odd… I am hosting a website on a Windows Server in IIS.
The code always works when the browser is Chrome. When using IE11 the result is that the widget does not display. The same page/code will work if I run the page under a dev environment (Visual Studio Development server).
So I am now giving some blame to an IIS setting… just can’t track it down.
The development documentation page for the widget works fine with IE11. So I inspected the source on that page, found that they do not do the Script the same way on that page as they provide for this when you create your widget, so I tried replacing my code with that, but still same problems. Works in Chrome, not in IE11… Again, works in IE11 when not running in IIS…
