How can one tell which Web rendering Engine is used by IE 11 and Edge
I have a very strange bug that only shows itself with one website. The bug always shows up after a PC reset or a clean install of Win 10 Pro. After a few weeks, the bugs will mysteriously disappear of its own accord.
It has been suggested that possibly, the bug is caused by a conflict between the web rendering engines used by Edge and IE 11, when both packages are running on a PC at the same time.
I am again faced with the bug after the latest clean install I did late last week. Today, I had cause to run IE 11 as an administrator and the bug vanished! I immediately put the theory to the test by restarting the PC and then trying to access the webpage with IE 11 ( no Edge running) and then again with IE 11 running as an administrator. But nothing ... I am at a loss to try and work out what triggered the correct response until I rebooted the machine.
Hence my question. If the issue is related to a conflict between the two web rendering engines then knowing which one is being used will help in being able to document the bug which causes web pages on only the ones site I access regularly to fail because the pages do not display properly, and response buttons on those pages do not work as they should.
