I tested this product for about 8 hours for renderosity. Tested both on win98se and win2000pro machines. Tested in the Pro Pack and Poser4. All worked fine on P4 standard figures as will as mike and vicky. I do admit I did not see the morphs at first. That is because I did not read the manual or follow the wizard properly. Make sure you are picking "groups" in the tree not materials. After "groups" pick a body part with a morph then click the mt icon. This is an awesome program. The best thing to come to Poser in along time. As a tester I can not keep the product and will be purchasing it today. Ron
