Every once in a while, you come across a Windows utility that makes you wonder “How did I live without this?” KatMouse is one of those utilities. This free, lightweight (using ~2 KB of memory) program allows your mouse’s scroll wheel to scroll whichever window the mouse cursor is currently over WITHOUT having to left-click on that window (to make it the active window) first.

It’s easier to see it action than to explain. Take a look at this 22-second video clip and you’ll see the advantage of using KatMouse:


As you can see, KatMouse can save you many mouse clicks and over time, make you more efficient, especially if you use multiple monitors and frequently switch between programs. It’s compatible with Windows 7, Vista, XP, 2000 and NT (Service Pack 3 and better). Download KatMouse and start wondering how you ever lived without it.
