Well, you aren't going to get consensus on this one. My Poser 5 works fine with the latest update. I think there are some improvements. I haven't tried the walk designer, so I can't tell you about that. Still can't load up V-3 and inject her with morphs (use Poser 4 for that) despite the update and despite a new computer with much more memory and power (I dread M-3 coming, I really do). Anyway, aside from that, I've found the update has been working well on Poser 5. Now here come the opposing forces. ;)
