Lately I’ve been really bothered by a weird bug where Chrome looses focus after scrolling via the mouse scroll wheel. The problem is with KatMouse, a simple program that makes the scroll wheel applicable to windows that are not focused, similar to how it works in Linux. Fortunately, the fix for this strange behavior is really easy and simple.
- Open the KatMouse settings and navigate to the Classes tab.
- Click the target window icon and drag it over an open Chrome window. Make sure you release the mouse when the cursor is over the main Chrome window (not over the tabs, for example).
- The Chrome window class should now appear in the KatMouse classes grid as shown below. Click Apply or OK and you should be golden.
I don’t know why this works, but I’m glad that it does. KatMouse is an awesome little tool that fixes a huge Windows annoyance.
