A method of operating a device having a touch-sensitive display includes displaying scrollable information elements on the touch-sensitive display and detecting a touch gesture from an input device on the touch-sensitive display. The touch gesture is classified as a flick gesture. If the flick gesture satisfies at least a first criterion reflecting a user intent to scroll the information elements in a single direction along a first of a pair of cardinal axes, the direction in which the information elements is scrolled is locked along the single direction. If the flick gesture satisfies the first criterion, any displacement of the information elements which has occurred along a second of the cardinal axes orthogonal to the first cardinal axis as a result of classifying the touch gesture as a flick gesture is undone. |
