Compulsive Undo Disorder - a condition wherein the afflicted person's first reaction to an undesired event  is to click "undo" wherever they are, regardless of whether they are working on a computer at that moment or not. Symptoms include reaching for a mouse at the dinner table when a beverage is spilled, or "tapping" the air with the index finger of the right hand several  times, accompanied by a sudden "sweeping" search of the eyes until the person realizes that the object they dropped, or the event, is not part of a 3D computer graphics program.
Telltale signs also include tapping the air after a roll of dice, after adding spices during the preparation of food, or changing the arrangement of furniture.
Studies at the University of California Medical Center at San Francisco and Johns Hopkins University in Baltimore, Maryland indicate that persons with a previous history of Compulsive Rewind Disorder are at an 85% greater risk of developing Compulsive Undo Disorder than the general public.
