This issue probably won’t affect many people since it only appears to happen when using a combination of three apps, Input Director, Google Chrome, and KatMouse (I mention all three in the post Software I Use Almost Every Day). The issue is while Google Chrome is in the foreground on the Input Director master machine, using the mouse wheel on the slave machine, also scrolls the Google Chrome window on the master. It’s slightly annoying.
So, on the off chance that you run Input Director, Chrome, and KatMouse, you can fix this issue by adding InputDirector.exe to the Applications tab in KatMouse settings. You can leave the settings as Default, just having InputDirector.exe listed fixes the problem.
