I havnt heard of a hex editor that has been able to turn this off... but there are a couple of critters you DONT want to turn hostile....
1. Stone biters (they have an annoying skill - beserk - that makes then a very tough enemy if they live long enough to go beserk)
2. Tibars (unless you have a happy archer, set to agressive, so it will automatically take out tibars without you having to tell it to do so. Having a melee char do this will only mean death, since he will run after the tibar the whole time... better to let the arrows do the running <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> )
There are ways to work around the hostile situation... Dont walk through peaceful areas in combat mode (vilages etc), just click once on the enemy to kill it (i know we tend to go click happy on a enemy, thinking it will kill it faster)...
With that in mind i have been able to go through the game numerous times without having angry critters (other than snails... i LOVE killing them, since they make a funny sound when they are hostile <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" /> )
