Nance: that's right, Poser 4.03, under Windows 2000. Jerr3D: I think Triarius used the ##### as a placeholder for the rest of the filename - I certainly haven't seen any hashes. Say if I'm saving a file named 'fred.pz3', then the temporary file (if it exists) will be named pzSav_fred.pz3. Triarius: Don't I know you from somewhere? :) I admit I have never tried using one of these pzSav_ files for real, that was just an assumption I made. A poor one by the look of it. My bad. :)
