When downloading a page the process starts and stops, the "spinning circle" stops spinning, then starts again. While typing the same thing happens. As I type the display stops and may not come back for a word or two. If I hover the mouse over a link I may get hand with a pointing finger or I may have to wait for the computer to catch up. When dragging the button on the right side down to scroll a page it does the same thing. The mouse continues down but the display stops and I have to go back and "pick up the button." A person smarter than me asked me if I used Norton and when I replied 'yes' they said that was my problem, something to do with resouces being hogged but he didn't know what. My laptop computer does the same thing and Norton is the main thing that the two have in common. Anyone have any ideas.
