A method including receiving a command to display a modal dialog. The modal dialog is displayed using both first and second scrolling frames. The first scrolling frame permits scrolling when a modal dialog height exceeds a first scrolling frame constraint. The second scrolling frame permits scrolling of a content section when a content section height exceeds a second scrolling frame constraint. The first scrolling frame constraint has a first and second priorities. The second scrolling frame constraint has a third priority. An orientation of the display screen is determined as being either in a portrait orientation or a landscape orientation.
