heyas; nance, you sound like me :) you have to press the button and wait a while. and no, it doesn't indicate it's doing anything. try on the primitives before you try on hair/figures. on some hair props, the fuzz appeared outside the mesh to the back. also, the re-scale dial may have something to do with it; make sure you don't turn that down, until you can see the hairy stuff. my hair never comes out this thick and full, even when i use the maximum number of layers. :/
