Ok, if Windows XP can shutdown without the MapleStoryGlobal,
the problem is not Windows XP, the problem located in MapleStoryGlobal.
So you don't need to worry about your computer or OS ...
it is the MapleStoryGlobal caused the problem ...
Just make sure you QUIT the game before you close WinXP,
or go to taskmanager to shutdown the computer.
all should be fine ...
