A method and apparatus that partitions a single display’s viewable area into at least two virtual viewable areas, and emulates the at least two virtual viewable areas as at least two emulated physical displays with an operating system such that the operating system behaves as if interfacing with at least two actual independent physical displays. A passageway is defined through the central wall. In response to a user interaction with the indicia, the proper subset of data field characters and at least one additional character from the set of data field characters are displayed in a secondary data field, wherein the proper subset of data field characters and the at least one additional character are simultaneously viewable by the user in the secondary data field. In doing so, the preconditioning functions allow for more accurate modeling of complex data relationships without increasing the complexity of the mathematical models. The invention is also directed to pharmaceutical compositions comprising said polymorphic crystal forms, methods of using them to treat respiratory diseases associated with \u03b22 adrenergic receptor activity and a process for preparing such polymorphic crystal forms. for well completion or stimulation in hydrocarbon recovery operations.
