Recently bought a MS mouse. Have found that when I move the scroll wheel up or down more than really slowly a little round icon appears with an up arrow and a down arrow. If the cursor is above the icon, the page automatically scrolls upward without stopping, and the reverse for the cursor being below that icon. It starts without warning and always goes farther than I want and it goes so fast it's difficult, at best, to react to it before I'm way past what I want to see. When I click, the thing goes away. Any way to totally delete this annoying feature other than throwing the mouse away and getting another Logitech? Thanks!
