The Guest or Playback users have some minor issues.
- User can enter values into the programmer but not clear them out. The user can turn Freeze on and off so they can get overridden.
- User can store a empty cue into a empty sequence. Store Seq x Cue x; where Seq x does not exist.
- User can Store empty Cue/Cue Parts into any sequence. Store Seq x Cue x Part x.
