Troops acting strangely

[johnhughthom]

My troops have started behaving strangely in EB, I have tried a clean install three or four times and it's still happening. Basically when I try to move my units they spread out like they are going into a loose formation and won't go where I want them, sometimes they just won't move other times they run off in a random direction. My cavalry just run towards where I send them and keep going, also in a loose formation. What files would I need to look into to see whats going on here? Thanks in advance for any help.
