If the script is installed in your poser menu it will run automatically for things designed to use it. I've never looked into it in detail, just had it installed for products that use it. I'm afraid I can't be of much help, I tried loading a v4, adding a lululee sexyskin, then loading an v4 and adding a sexyskin to this and all worked fine. I'll admit I'm a bit of a defeatist when it comes to poser problems, if at first I don't succeed, well there is usually a work around! Sorry . John
