KatMouse (remove only)  by Eduard Hiti
Publisher's description - “The prime purpose of the KatMouse utility is to enhance the functionality of mice with a scroll wheel, offering "universal" scrolling: moving the mouse wheel will scroll the window directly beneath the mouse cursor (not the one with the keyboard focus, which is default on Windows).”
