What I would do is click on the offending box, then do a search for "100" (for 100% transparency) as a material. In my system it is C: Users Poser 11 Content Runtime libraries Materials Cartoon BikerGirl 100% Transparent.mz5) Then I would apply the 100% transparency to the box. See if that works. (Yikes! I tried to put spaces before and after the slashes to make them show up. It didn't work)
