This also affects me on a fresh install of xubuntu-14.04.3-desktop-amd64 with all updates. The command xfce4-panel --version reports "xfce4-panel 4.11.0 (Xfce 4.10)".
A workaround that seems to have fixed it for me is to insert a separator as the last item in my panel (to the right of the "Action Buttons" item). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1049450 Title: Fails trying to hide the xfce4-panel panel 1 To manage notifications about this bug go to: https://bugs.launchpad.net/xfce4-panel/+bug/1049450/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
