/// PA gains focus and it determines if any of the data sources have been updated
/// since it lost focus, PA will determine that all skipped data sources have not
/// been updated. Normally, the last modification date on a data source is set when
/// the data source is read. But if the data source is skipped, then the last
/// modification date will not get set properly and will cause PA to keep re-reading
/// data sources each time the program becomes active. Hence setting the data to
