I see what the problem is. I am using Chrome. After I use the CMS and go back index-bak.php, the Live Edit feature is on and creates the effect you see in the screen grab below. It looks like the little 'Edit' buttons on the left side of the screen create the misalignment. If you click Hide Edits, it's fine and it's fine for any visitor not using the CMS Admin. It would be nice if it didn't do that, but it's something we can live with if it need be. If we could have that screen to either default to hiding the edits or some other simple tweak, that would be good. Otherwise, we can leave it be.
