There's an invisible Google Chrome button in the middle of my blitz board!

And when it's there, I'm unable to make blitz moves.  When I click on the origination square for the move, a full-screen Google Chrome download screen appears.  I just had to abandon a won blitz game because I couldn't make any moves, and when I closed the Chrome screen, the board reappeared, but the clocks at the top and bottom were gone, and the invisible Chrome button was still there.  You folks need to fix this RTF now.  Better yet, why don't you get rid of that popup entirely?  How do you think I feel about having to click it closed every time I log in?  It's like you're trying to shame me for using a browser other than Chrome or Firefox.  I'm a 63 y.o. retired lawyer/judge and I've been using Internet Explorer since the internet was born, and if I ever change browsers, it will be on my initiative, not on account of nagging from the likes of you.  This continued nagging has reached the point of disrespect.  The problem isn't IE, the problem is chess.com.  DO YOU UNDERSTAND ME?  Can I get a 5x5 10-4 from you sweet sister?   

This problem exists when playing the computer, too.  I just tried it, was good for 13 moves, then the Chrome button kicked in and I was paralyzed.  The other thing I just did was register on lichess.org so that I will have an alternative for wasting time on blitz chess.
