I have a Logitech M705 mouse, which works perfectly on every other application except Evernote. That tells me that the problem is with Evernote, not my mouse. It multiples every setting I give the mouse. If I set the mouse to scroll by 1 line, Evernote scrolls 4. I set 3 lines it scrolls half a page. I set 6 lines is scrolls over a full page. And if I set it to scroll a full page it scrolls over 2 1/2 pages. If I go to any other program on my PC it does exactly what I set the mouse to scroll at. The problem is with Evernote.
