I do see some difference (VFP 6): when it it ReadOnly, there is no visual clue (in itself confusing); when it is disabled, the text gets gray; when it is only NULL, the text is normal, but the square is gray. While there is a difference, I agree that it is confusing.
One alternative might be to change the Picture dynamically (when the value is NULL), but that seems complicated for something that should really be quite simple. If you want to try it, you may want to change the Picture to a gray square for the third state (NULL or 2). I think that would be less confusing.
