There is a graphic in the About dialog that may be a little too risque to some for whatever reason, so it is hidden by default. You can toggle the display of the graphic by holding down the Alt, Ctrl, and Shift keys when clicking the About button. The state of the About dialog will be remembered until it is toggled again.
Of course, do not allow this 'About Note.txt' file to be accessible to someone who you do not want to know about the graphic.
