Going for "step or two" that bug I remember from original fallout 3, and I still dunno if it must be so or it's really a bug, and in the game menu or opening pip-boy i feel difficulty using mouse cursor, it somehow changes mouse sensivity to max, anyone experiencing that too?
Yes that problem is related to this post, please post in it.
