    Set the active script to None if the current window is deactivated
    
    This condition is typically immediately followed by some other accessible
    event which will cause the new active script to be set correctly. Failing
    that (e.g. an inaccessible window gets focus), the event manager will set
    the script to the default script. This should prevent things like the
    terminal script continuing to spew output when a new workspace with no
    accessible applications gains focus.
