Norton Ghost should be there only when I want it

I just uninstalled my brand-new Ghost, because even though I disabled it in config settings, it insists on loading automatically.  I have it on a laptop and do not want it running when I am in the field.  Seems like I should determine when it's running, not the software.  Am I missing something here?  I saw a note about editing the registry, but that seems ridiculous when I simply don't want it to start up when I boot.  Any thoughts?
