Hi John,

I tested in Microsoft Minesweeper, and now see that you are correct. If a
square is flagged is does not get revealed.

I'm not sure how much I like that concept. In my mind, the Flags are there
to help you remember which squares you have already determined were mines.
If you open up a square with " " or 0 mines around it, you know for certain
that the surrounding blocks are all clear. If one of those blocks was
flagged, it was incorrectly flagged.

Should the incorrect flag be left there, despite the fact the game is
basically telling you "There is no mine there" ?

I guess that would be a question for real Minesweeper enthusiasts.

Best,
George
