Just noticed something when using Safari. If you leave a comment, the window doesn't close when clicking on it. It does work in this manner if you don't leave a comment. Also as vangogh said above, the close window link does not work either. You can close it following his method though. I guess this should also be posted in the Community forum just in case...
