Mark,
3.14! Purple-ish, pink-ish box.. no layers! I do remember it.. (actually, I thought is was 3.4)
Used to be able to set the tops of the corners of wall independently!
Had a little matrix of 16 numbers that really represented LAYER COMBOs... So any entity could belong to MORE than one of these at a time..
Sorry.. for waxing nostalgic... But I do remember back then.
