Occasionally, you may see a blinking orange button at the bottom of the screen on the gray "Task Bar." (The Task Bar shows you all the programs that are open at that moment.) There may also be a blinking Title Bar on one of the windows. This means that the computer requires some action on your part. Just click (or double-click) on the blinking orange button to bring up a "dialog box" where you can click on OK or Cancel (or some other button).
