It happens with all the features articles, the wrapper, lytebox etc and it shows only if you are a registered member to the site.
It's the User Menu box (mod_mainmenu is the module)
It should only show if the Main Menu is also on that page, but it seems to be on every page. This was a fresh install, with nothing else added.
Screenshot of settings in admin:

At the front, the s5 box has the login box at the top left of the page
Also, there's a admin link at the top directly to the CPanel, and it's viewable by everyone, member or not. I changed it to registered, but there isn't a setting for admins so only they can view it, just a "special" setting which doesn't seem to do anything.
Oh, another minor thing, there's a small line display problem at the very bottom of the page where the 8 boxes are, the corners for the border line are 2 pixels, while the line between them are 1 pixel. Using the latest Firefox, but just a CSS thing that is easy to fix myself.
Pretty stable template, and really like it as a design.
