That is why you can't remove from memory the startup disk, the system needs to be able to find itself. Font/DA mover works well, but have you noticed that it doesn't have a DA menu? Ever wonder why? Ever wonder why Suitcase and Font/DA Juggler warn when you are about to close a font file? Because weird things happen when you change the system file when it is in use. By the way, weird things happen to most files when they are already open and something else comes along and trys to change them. That's also (I think) why you can't launch the same application more than once over a network or Multifinder (unless it is a multiuser application, but they might have multiple copies to get around that, I wouldn't know though).
