I have a dell about two years old and my window is windows XP. Before my computer crashed, I could scroll down a page using any button or slide and my screen remained stable and in focus. Now when I scroll down the page, it turns to liquid (out of focus) as I scroll and then when it stops, all is good. It isn't that problematic, but it is bothersome....any ideas?
