If you load a character into the document window, then do; File > Save, this will save the file as a pz3. This file should load the character ok ON YOUR MACHINE. It does not contain all the information necessary to to load the character on another machine. A pz3 does not contain the geometry (*.obj), or map files (such as textures, bumps, and trans maps), it only containes paths pointing to the location of these files on your HDD. If this is not working for you, then there may be a problem with your Poser instillation, and you could try reinstalling Poser. If you just want to save a character for your future use, save it to a Figures pallet, use the "+" at the bottom of the pallet to add add your character.
