L2 Walker config

Hi, im using Walker IG with a human wizard, and i have these problems:

*I don't know how to configure it so i can heal myself, sometimes i heal mobs :S
*I don't want to use Direct attacks but sometimes it does, i'm not shure why.
*My char doesn't flee like it should, it just stand there.

Ok, i manage to fix the first and third problem, but i still hit in melee sometimes :S
