How do I fix this problem? A link to firefox-sync immediately caused desktop screen picture to begin a slow sea-sick roll. I am running my AV program now and screen is still on the high seas.
From this page, How to Set Your Home Page to Your Favorite Web Site I clinked on "web browser" Web Browser and that immediately gave me the 'sea sick' roll to the screen. My AV has not found anything wrong, but it is still running. The speed of the rolling sea-sick screen seems to vary with typing speed. It slows down when I keep my hands off the keyboard. The mouse has the same motion problem.
