There is a place to leave comments, with the tab "Comment using..." But when I click on Yahoo! in the drop-down box, I am taken to a BLANK Facebook page. And that is the end. I have an extra window now open, and nothing happens. Why? If I click on Facebook, I have to put in my Facebook password (even if I am already signed into Facebook), and then.... blank page. The end. What is going on? Pop-up blockers off, security on the lowest.
