A:Answer After submitting an answer previously, I found another possible solution. In an online Q and A, a reader responded that sometimes the numeric keypad on the right is sensitive to the vibration of typing, and can cause the cursor to jump around. He suggested pressing the "num lock" key at the top of the numeric keypad to turn it off. See if that works. Don't forget to turn it back on if you need to use the keypad! I hope this helps!
