DOS version changes working directory
This is a very very minor issue, but still, it's an issue... when you run the DOS version of 1.2.0p1 from a directory say C:\ADOM, you play the game, and you die, the game exits to the DOS prompt in the directory C:\ADOM\ADOM_DAT\TMPDAT. So in order to play again, you have to "cd .." two times before typing "adom" again.
