Did I miss your question? I do not have SP downloaded yet, just trying to help.
Well... Yes, it's not really what I mean. Imagine banana shape. Convex object is banana with both tips connected by line so the result is sort of D-letter. That's okay for me, because it's not that large difference. However, in my case, whole banana works like a box, although if I open banana file, it displays properly D-shape.
