KO Performs an illegal op sometimes. I can be in the middle of xp'ing but most of the time its when I'm afk in merchant. Do I need to disable everything in background if I leave KO unattended for a few hours or..... what is deal.

I got a slow PC... AMD Barton :P 1.8ghz but I have 2.5gb of RAM so... can't really figure out a problem here any help would be nice.

Thanks in advance
