Good morning to all of you that replied to this. I appreciate all that you have responded with here. But quite frankly I am well aware of planning, budgets, testing etc. If I had been in charge of this, I would have started working in all this two or more years ago. But what is, is. Nor do I need suggestions on updating the HTML or JS or frameworks, etc. All of that is pretty straightforward. What I was looking for was any information from those people who have dealt with those truly IE specific technology issues when moving to a modern browser like Edge-chromium. Things like, has anyone else had to deal with the - - noframemerging issue and what you did to overcome this. Or replacing the IE specific WebBrowser control in a WinForms app with the WebView2 control, especially when the WebView2 control does not support IE Mode. Maybe this is too technical for the Lounge. In that case contact me directly. I can get all of these together and put out an article here for anyone else dealing with this (giving credit where credit is due). Thanks again...
