Since updating to 10.4.2, my MX1000's left side-scroll rock (of the scroll wheel) now activates Spotlight in the menubar. What the? How do I disable that? I don't have any drivers installed for it. And don't tell me to install the Logitech drivers, because I won't. And don't ask why either. Anyone else with a MX1000 or any mouse with rocking (side-scrolling) wheels have this issue?
