I may be duplicating a comment but my last comment doesn't appear as far as I can tell (after refreshing my browser window) so I will try again.
The gist of the issue is that no matter what different colors I use for the border and the actual shape, the opacity selected becomes the same for both. In other words if I set the main shape opacity to "0%" to make the shape like a clear window, the border also disappears. Even I go back to the borer and raise the opacity selection to "100%", then the shape becomes opaque again and obscures the text it is intended to be emphasizing. What am I missing?
