The whole problem is that this prescribed route just does not work. It won't change from the current setting of Internet Explorer. I believe it will change to Edge (the preferred Windows 10 Browser), which I like even less than Internet, but doubt if that will then permit further change either. Some time ago I did find a method, perhaps by accident, which worked but I have now forgotten it and I am stuck. The reason I like Chrome is that the 'autofill' function seems better.
