Entering a single quote character gives a strange pop-up screen
When I enter a single quote character a strange Duolingo pop-up screen appears. This has only started happening today and appears to be happening in all the languages I am doing and even in the search box in this discussion forum. Is it just me or is anybody else experiencing this?
Just in case anybody is interested, my problem was indeed caused by Evernote Web Clipper. Somehow the keyboard shortcuts had been switched on and the keyboard short cut for Start Web Clipper is ' (single quote). Now that I have turned off the keyboard shortcuts I don't have the problem.
