WizMouse causes your mouse wheel to scroll the window under the mouse pointer instead of the currently focused window. You don't have to click on a window to focus it before you're able to scroll it with the mouse wheel. It can also optionally enable mouse wheel functionality in applications that do not support mouse wheels.
What's new in this version:
Version 1.6 has X1 and X2 mouse buttons working correctly when used with the mouse wheel and automatic rehooking of WizMouse is now configurable via a new 'Re-hook WizMouse if mouse capture lost' option.
