I found that, with the crack, when you start crashday, it just opens up a window (as if your playing a modern game but in a window) with blackness in it, you can still hear the sound
It certainly is NOT an MS-DOS box.
All you need to is wait about 1 min, then press ALT-TAB to switch it back to giving it windows focus a couple of times then you could see the graphics...
Then press ALT-ENTER
This will make it full screen
I still had my MSN icon flickering through the window, just setup the graphic options properly in the game, exit
Restart the game and everything is
