Okay, props to Richard Haseltine who just solved this big LW mystery (by posting in one of my threads over at the DAZ forums).  Apparently you need to have the "Zbrush OBJ" option in the "General Options" section checked.  Something about doing so reverts the importer/exporter functions back to the 9.3 and earlier versions of LW.

tips hat off in recognition of Richard Haseltine's diligence in solving this LW mystery
