And BTW, on the 16-bit version, open minsweeper and immediately type xyzzy[enter][shift] The top left pixel will change to black when you are over a mine and to white when you are over a free space. Does NOT work with 32 bit.
On freecell, hit [ctrl][shift][f10] and take a peek at that.
On Solitaire, [ctrl][alt][shift]-and a click will turn only 1 card even when in 3 click vegas mode.
I know, I know... It isn't fun if you cheat, but I remember reading those a LONG time ago...
Oh yeah, in Minesweeper (32 bit), if you hold on the escape key when you clear a mine, the timer stops.
