Using Sharepoint MOSS 2007, there are a couple of pages/sub sites that need to be hidden. When going into change the navigation, I set the page/sub site to be hidden and save. when I go back to have a look to see if in fact the page/sub site has been hidden or not, it hasn't.
Don't know whether this could be to do with the pages/subsites having already been moved? The pages/sub sites don't seem to want to be hidden from the part of the navigation where they're not needed.
