This is a little-known cheat, probably because no one bothered to look for it in the first place...
Open Minesweeper with all other apps minimized. type 'xyzzy' and hold shift for a second. now when you mouse-over individual squares, a black or white pixel appears in the top left-hand corner. black=mine, white=safe. sadly enough, people bet on minesweeper times, so i've been raking in the winnings (i.e. a couple sodas and a dollar)
