Here is HexSweeper 1.66.  It's a lot faster than 1.0 at many things,
and somewhat more playable as a game.

HexSweeper is a game a bit like the VMS (or Microsoft Windows) minesweeper
game, except that instead of a rectangular grid there's a grid of hexagons.

Known problems:
    * There's no high score yet, and no Properties window.
    * Do not go directly from Texas Scale to Welsh Cottage Scale!
      (perhaps the program should prevent this)
 
If you do get a problem, press L1 (STOP) if the mouse stops working, and
then either use pskill or pam to get rid of the Hex ps processes.  I can
mail you an effective pskill if you don't have it.

Don't be discouraged by that warning - HexSweeper is fun to play with,
and it works in both colour and mono.  It uses your Window colour, so if
you want, bring up props (Workspace menu->Properties) and change the colours!

Please tell me if you try HexSweeper.
