I guess some Windows update has caused this.
I'm getting this message on most sites and it started yesterday.
It's a pest, is there a way to stop these messages?
See the bottom of the screen shot.
Also, I'm getting a popup message from IE (or Windows) when visiting www dot politico dot com.
So, either that site just started popups today (which is highly unlikely)
or suddenly IE or Windows is not blocking them, and I get a message to allow or disallow the popup.
