For some reason, my copy of the Logitech Setpoint software keeps changing how many lines it scrolls at. I set it at 3, do some stuff and it's changed itself to 7 lines, I change it back to 3, it gets up to 9, I go back to 3, it goes back to 6. Each time I set it, I make sure to apply the settings, then hit ok and the window goes away. I uninstalled 4.04, rebooted as prompted then installed the most current version which is 4.24 and it's still fucking happening. Sometimes it works fine for 2 days, next time it's 2 hours or 20 minutes, sometimes during a single browsing session of 5 minutes it changes. Anyone seen this before or got any ideas?
