I agree. Imho, poses should never have MT references (unless it states this and it is for a specific reason and part of the product) or to anything (definitely not hair!!). The references should only be to create the pose. And I also think all products should be set for version 4 to ensure the largest no. of people can use it without getting that "newer file" error msg. It is also very easy to change the version no. and anyone making poses should set the version no. to 4 so those buying their poses use them regardless of what version of Poser is set. So if you use PPP or P5 to create poses you should just make sure your pz2 file has the correct version no. To change the version just open the file up in a good text editor. Where it has version no. change it to 4 or 4.01. Hope that helps ~Diane
