Or in my case:
You see an enemy. You press spacebar to pause, you hover your pointer over the enemy, you see his red circle light up, you click. Chosen characters will face him. Press spacebar to unpause. Character runs past enemy and just stands there with his back to him. Enemy proceeds to kill character.

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.
