I will often click on a button expecting it to be clicked but instead all that happens is the application it is in becomes active, and I have to click again to actually click the button. It would be nice if this second click wasn't needed, which leads me to my question:
How can I make it so that when I move the mouse cursor over an inactive window, it becomes active?

This is freely possible for the Terminal and X11 :
Or, OS-wise, with a utility that seems to fit your needs, called MondoMouse.
