My awkward solution was to use a different mail program, Mozilla Thunderbird, on another computer,
to compose and format emails with copied and pasted web articles (no problem with retaining hyperlinks), sending to myself, and then retrieving them on my main computer (links intact) -- I could then forward them without loss of the hyperlinks. Lots more work involved, since I send articles to my email list every day. So I'm considering the suggestion to backpedal to IE 10.
I also did something like that but it was a lot of extra work.
I uninstalled IE11 and now everything's ok.
But what is Microsoft doing?
