Tangent Edges in Creo2
A slightly trivial subject, and quite possibly an even more trivial answer, but: how do I get Creo2 to show dimmed tangent edges in solid shaded view, like Wildfire used to? Now it looks like Catia, and tbh it's ugly! 
Options -> Entity Display allows me to choose from a variety of options for tangent edges - but it doesn't seem to respond when I change the setting.
