Temporary remedy to this annoyance is logging into "Gnome Classic (No Effects)" (I'm on 11.10), and then do the settings.
Is this related to HW acceleration? To test whether this affects you, go to any You Tube video, right-click on it when the playback starts, then select "Settings". Adobe Flash settings dialogue will show. Try closing it by clicking on "Close" button. If the dialogue does not respond, the bug affects you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/865672 Title: Adobe flash settings 'allow-deny' dialogue does not respond To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/adobe-flashplugin/+bug/865672/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
