ProgressReportingDialog: It appears that when the progress dialog's content, as seen by the user, only updates when the progress value changes and NOT when the label's text is changed.  So, when the progress event is received, update the label's text first and then set the progress value.  This should fix a problem with the dialog's label text being 'one event behind' the most recent event.
