I get error message (Error while copying "/") with details (Error opening file "/": is a directory). Keep aligned is turned off. This only happens when trying to reposition url related launchers. Some of the launchers were created by using Firefox "Create Deskcut" and some with the older Nautilus "Create-Launcher" script.
