Abstract
A method of displaying messages on handheld devices. The device displays messages in a scrollable viewport of vertically arranged fields. Date separators inserted into the vertically arranged list of messages to enable the user to associate the messages with a date. The date separators have “sticky” operation, meaning that the device ensures a date separator always appears within the viewport, even when the viewport has been scrolled to the middle of a long list of messages all associated with the same date. The device may ensure that the top field of the viewport always contains a date separator associated with the message immediately below.
