Hmmm - it appears that "it is back"?!!? Perhaps it was just a loose IEEE1394
cable? Perhaps it was just a malfunctioning camera? Maybe it was just the
sequence in which I initiated everything and then crossed my fingers? The camera
was running off of its AC adapter so it sure wasn't a problem with power. SIGH!
