I had to adjust my code to recognize the browser like this:

        ' Based on the browser
        Select Case oBrowser.Browser

            ' Microsoft Internet Explorer
            ' Recent version of Internet Explorer returns InternetExplorer (11)
            Case "InternetExplorer", "IE"

At first, I had IE. That used to work for a few years. Then, I discovered the value returned was InternetExplorer. So, I adjusted for that. I assumed something got changed in the .NET Framework in the way this is now returned. But, actually, this is coming from the browser information and .NET Framework simply use that as is. So, I had to add IE back in there. Basically, it seems the longer word is returned from recent version of Internet Explorer only. Can someone confirm that?
