I am reading emails and suddenly a popup occurs like below asking if I want to add the mail sender to Google+ contacts
I cannot get rid of it. I certainly don't want to add this sender into contacts but there is no way to quit this popup. I have to resort to logging out of gmail and going back in. Has anyone else noticed this and is there a way to quit the popup without signing out. Its a real pain you cannot move it on screen ALT-F4 doesn't get rid of it.
Help!
