the right-mouse button in windows gets a good workout, but that poor old middle button on three-button mice gets ignored. cool mouse rectifies that. once it's running in your system tray, this great tool lets you use your middle button to pop up the start menu underneath the mouse cursor, minimize windows to the system tray, roll up windows to their title bar, and more. customize any window to have its own features layout. the "fast folders" feature can display a pop-up menu with your favorite folders for easy navigating in open/save dialogs. you can also make the middle button simulate a double click, scroll the current window, and take advantage of fast program configuration through hotkeys. even if you have a two-button mouse, your right button can duplicate cool mouse's functions when you press the scroll lock key.
