electra666 What you are probably having happen is the sims will get into moods that have a different walk than what you assigned in CAS. Basically, the only time the assigned walk happens is when the sim is happy as far as I can tell. If the sim gets angry, confident, etc., then the walk style changes to the one associated with the mood the sim happens to be in. In my experience, it seems that the sims use other walks more than the one assigned to them in CAS in my game, so what you are seeing is normal and just the way the game works.
Hope this helps.
