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 126.96.36.199 runs at a higher priority level to keep mouse movement smooth on slower PCs.
