Yes, several nude figures are included in Posers 4-5, along with a wide assortment of outfits with which one can play dress-up. If that truly concerns you, however, you can delete the nude figures from the libraries before handing the computer over to your daughter.

Every version of Poser has had its share of bugs, quirks, and limitations, but most of us have learned to live with them. The best advice I can give you is to install the latest patches or service releases, and then seek help here in the forums should any problems occur.
