In the current system, when tutor mode is on, 

Ordinary move

1)  when you ask for the dice to be rolled gnubg knows you aren't going
    to double and does a check (at whatever level you've asked it to
    use) on your cube action.

2)  when you've moved your pieces and click on the dice to indicate
    you've completed your move, and does a chequer analysis

Response to a double:

when you take/pass, gnubg does the analysis

The pop-up window provides two things:

It gives you a way to rethink an erroneous move

It stops gnubg from playing while you see the message about your
potential mistake.

If you don't have some method of confirming that the user has seen the
message, such as the proposal to have a short message on the status
bar, then as soon as you commit to rolling the dice, the status bar
displays your roll, overwriting the cube analysis. Wehn you commit a move,
gnubg will start its move. This will overwrite the status message as
well. In effect, for most moves, gnubg's rating of the move will
disappear before you can see it.
