Seems when starting every item in the Catalog is checked, make sure the path still is available.
If not, for a drive a little red cross (I think, dont remember that well
But for a folder, the icon is "lost" (unknown file type icon) when the path is not found, and even when it's back the icon stays like that. Only way to get it back is using properties and "changing" it (like adding/removing the last \ so its "reloaded" I guess)
