There's something strange happening with my computer. I’ve noticed it on and off acting odd, like it will scroll on its own. For example, if I scroll up or down, the screen will move. Is my computer haunted? Well, today I checked under Internet Properties ---> Security Settings and it’s moving! Like if I click on ‘apply’ to save the setting to ‘Medium High’ it scrolls all over the place. Low, Medium, High. What is going on here? Has anyone experienced this problem?
