every time I return to my computer after I goes into screensaver and blanking, a refresh of any web page with flash content hangs with a plug-in isn't responding. This started with google-chrome-30.0.1599.22_beta1
Problem seem to resolved itself. Could have been site maintenance on tracking sites over holiday weekend or another update. At any rate the problem has disappeared and has nothing to do with gnome-screensaver. Please mark resolved. I will repost if it reappears.
