I love Poser 7, it was however rather cheap the other day when I was making custom morphs for a figure.
Working with magnets for a couple of hours and saving to a PZ3 every ten minutes, when I was done and having removed the magnets I was gonna save the the figure one last time to my PZ3. 
It saved in about 1 second and then it wouldnt open again, checked filesize at 437Kb (pretty small for a heavely morphed V4).

Part from that I love it :-)
