Bossing and crashes.

Another thing could be the BlackCipher thing that's also running in the background. It sometimes hogs up a lot of your CPU, almost as much as MapleStory does depending on what you're doing.

I notice that sometimes, BlackCipher can disappear or crash on its own and it takes MapleStory down with it a little after; No error/pop-up/Maplestory has stopped working messages. MS just crashes onto my desktop. Not sure how you can fix that.
