I have a slight issue in which when I use my KVM switch to switch my keyboard, mouse, and moniter use to my server system, the server always has no problem with the mouse. However, when I switch back to my computer, I can no longer use the Logitech's mouse scrolling feature. This didn't happen before on my old mouse so I don't know what's goin on. My Logitech mouse is the MX518 Gamer's Mouse. My old mouse was just a regular 3 button mouse (2 buttons and the scroll button). Any help?
