A method includes determining that an overlay is to be displayed at a predetermined area on a touch-sensitive display, the overlay being operable to be closed in response to a user providing a touch input at predetermined location within the predetermined area of the overlay; detecting the presence of a digit proximate to a surface of the touch-sensitive display; determining a digit location, the digit location being a location on the surface of the touch-sensitive display to which the digit is proximate; comparing the digit location with the predetermined location; and if the digit location corresponds to the predetermined location, modifying the operation of the overlay so as to prevent closure of the overlay in response to a touch input provided at the predetermined location.
