I just upgraded from 4.0.3 to 4.0.5, and now when I select "Full Display in Section Page" and have images in that CMS article, they don't resize at all to fit my homepage. They overlap other articles and go underneath widgets on the side. Big mess.
In 4.0.3 I could Display Full Articles with an image and it would automatically resize to fit the space for that article on my homepage. Then if you opened that article, it would be the proper full size. Now I have to select NO for "full display in section page", which is NOT a solution as I can't display multiple images in a single article on my front page.
