I'm attempting to follow the guidance in this MSDN listing:

msdn.microsoft.com/.../...PointHowToApplyBrand.asp

and have gotten the look and feel of my initial portal page to a point where I am satisfied moving it to the other areas of the portal. When I make the modifications to the default.aspx files of the other areas (for example, News), it doesn't seem to work. It seems like flashes for a moment, but then the default layout re-appears. Any ideas?
