Fooling around on my xp home desktop, I inadvertantly selected the desktop 'Arrange icons by>' 'lock web items on desktop' switch (checked). Now my background is divided with a vertically split white screen that can be wiped with the mouse to within about an inch of the right edge screen (this feature is to load web content as part of the background). Since I don't really want this, I deselected (unchecked) the 'lock web items on desktop' switch, but still have the annoying split screen feature and it won't go back to normal. How can I turn this feature off??
