Hi TG, if your program crashed, the next time you load your software it should ask you if you want to restore your previous work, if you save yes, you may get back what you have been working on.

I haven't found a way to lock grabbing a group and moving it in one direction,  I too need to rotate the object, grab the puppy again and adjust it.   

That doesn't mean it's not there just that I haven't found it yet!!

Have you found a way to apply paint then save it as a uv texture map that is recognized by Poser, Vue or Carrara.  When I save the "colored" .obj , the .obj comes out as default gray in my other programs.  Jan
