To me this looks like you are using a browser that is not supported. In my experience, they (well, I am talking only about Firefox) seem to work well but occasionally you get weird results.
PS It's a bit late but stumbled upon your post only now, so sorry for the late reply.
Do you open the page in your browser or did you create a shortcut on your desktop?
We faced the same issues with the shortcut, but we had no problems opening it directly in the browser.
