Bah! I\'ve had the same problem. I killed the rogue in Akkaio\'s warehouse to help out a new player, and after that, I was auto-attacking everything. If I was even close to a monster, I would go into full-defense mode and begin attacking. It wasn\'t until I left the city that it stopped.
It\'s not normally a big problem for me since I don\'t fight often, but it was then and I know it\'s annoying for other players who experience it. It was frustrating for me as I was trying to teach the new player how to attack something, and instead I kept on \"taking\" the rat.
