Katmouse is a program that is kind of hard to explain. What it does is very useful, but you don’t really realize until you’re without it. In a nutshell, it enhances how your mouses scroll wheel works. It lets you scroll any window that is under your cursor. Usually, a window will only scroll if it is active, or on top. Katmouse changes that.

After you have it downloaded, just run it and continue with the installation. I recommend selecting Yes when it asks to put a shortcut in your startup folder. This will make it start up with Windows. Click Yes when it asks you to run the program. There should be a new icon in your tray, shown below. Right click it and click Settings.

The Katmouse Properties window will pop up. Uncheck Show Tray Icon because you don’t really need it there all the time, and you can change the properties when you want by going to Start -> All Programs -> Startup and selecting Katmouse.

Click on the Wheel Button tab, shown below. What this does is make a window go below another window when you click with your scroll button on your mouse. I find this more annoying than useful, so I set it to None of the buttons. But you may find it useful, so experiment for a while.

The other two tabs, Applications and Classes, I haven’t found much use for. But they’re explained in the Usage section of the Katmouse home page.

KatMouse will run on NT (SP3+), Windows 2000, XP and Vista, but not 9x and ME.

I hope you enjoy the functionality this small program gives you!
