actually I think I figured out the issue...when you make a menu "blog category" type link, you get your blog layout style and when you click on a "Read More" link from the intros, you get the full page article. However, when a menu item does not exist for this or for an article, the new show pro has no layout attributes to display like a normal menu link would, so therefore it loads the article in the page where the module is published to.
So in a nutshell, if a person does not have a menu link on a menu somewhere that points to the category >> Articles, it will load the article in-page. But if one was to create a menu link to the category, whether on a live menu or a "hidden" menu, then the news show has something to display in a blog category format.
Hope that made sense? I doubt many will have a scenario where no menu link exists while using the news show pro to load articles from a hidden category. I just remembered I had to do this once a couple years ago, where I had to create a hidden menu, which I also used for other pages that were not being linked to directly from a menu item, such as in-page links, or a thank you page after one submits a form (when needing modules on that "thank you" page, because you needed menu items to publish modules.
Ok, time for coffee!
