There is an undo up in the Edit menu, but it doesn't always work. I've used it when I accidentally posed the shirt instead of the body, for instance. It will return it back to it's starting point before you moved the wrong piece. I can't imagine my life WITHOUT Poser now. I'm a hard core addict. I work with it a little bit everyday. It's just so much fun. Creating people out of your imagination is just so unbelievable. I use it to help me visualize the characters I create in my written stories. I've actually discovered things about my characters I never knew until I created them in Poser. I highly recommend it. I'm looking forward to Poser 5. I only hope it's all we're expecting. Melanie
