Brand new eleitebook 850 g4. My mouse will not scroll properly in youtube, facebook or amazon. Will not scroll in google sometimes. Screen does nothing when clicking the arrows or scrolling the wheel for about 4 seconds, then either moves 1/3 of a page, or all the way to the bottom. Have uninstalled and re-installed all mouse drivers. Logitech unifying usb dongle.Touchpad does the same thing. after about 5 minutes, it gets better - sometimes. Please help before I have to destroy state property.
