Is your character in peace mode? If he is, either switch him to fight mode, or click on an enemy, and simply wait a moment for the main character to stop, pull out his weapon and actually hit an enemy.
Er, that could explain things I suppose. Can you not attack manually if you're in peace mode? I'll try it when I get home anyway. The only thing is, I have been successfully hitting the enemy occasionally, about 25% of the times I try to attack. I would certainly expect to be able to manually attack when auto-attack is turned off.
I'll try it anyway.
