Fixed Width Locked
With both the eatlon and jqui themes I have unchecked the "Fixed Width" box under "Look and Feel -> General Layout Options" and it looks to have no effect. My understanding is that the center panel constraints would be lifted once this box was unchecked enabling the left and right menus to expand to the browser edges.
I've been looking through the documentation but am having trouble finding anything specific to this option.
