the trick to naming a bone in Poser 5 is to hit enter key after typing in the name each time. I tend to use the setup room as little as possible, the only times I use the setup room is if I want to create figures that contain the joints of one figure but have added joints, like if I am doing bodyhandles in clothing, for that the setup room is generally very useful, otherwise I avoid it. as for the joint editor I prefer the P5 joint editor to both the P6 and P7 ones, as they are both more buggy. unfortunately due to the slight changes in how joints work in poser starting with P6 I have been forced to move up.
