What a great jump to make! Forgetting whatever 'bugs" you might encounter, the improvements since Poser 4 are really worth having. If you haven't noticed them yourself already here are a couple worth noting: When you open the drop down menu of body parts there is a little tick mark showing you which body part you currently have selected. This is great when trying to quickly orient yourself among so many variables both L and R. And that drop down list can now be accessed from the parameters window so you don't have to slide your curser all the way back to the main window. The up and down arrow keys can be used to move up and down through the body parts of the first figure. Handy if you are doing pose design for one character and moving through each body part and don't want to keep going to the drop down menu. That won't work if you have many characters, the scroll through only seems to work with the first character. Well, you've probably already noticed lots of other groovy attributes yourself. You've got a lot of fun ahead of you.
