The sensible workflow should be: memory card is mounted, Ingest Dialog Box pops up, Ingest from Selection is chosen, AND THEN the contact sheet is created. Images are selected and then an Ingest button is chosen. This should all be done from inside the Ingest dialog box without having to go to the "File, Edit, Image ..." tool bar.
