Found work-around for browser issue on www.stackoverflow.com
I mentioned in a prior post that Youtube had cut support for older versions of Internet Explorer which is used by the web browser control in C#. I found a workaround on the Stack Overflow website. You can call a Process that launches Microsoft Edge. You just give it the url and Microsoft Edge would start and open the url you called.
While I would prefer that the web page would open inside the app, this is the next best thing.
