The 4.0 version of The MacArthur Topical Bible and What Does the Bibel Say About cannot be navigated from the reference bar by topic, just by page number. In 3.0 one could type a topic into the reference window and jump to the topic if it existed. For a topical reference this function needs to be restored to both these resources.
*This is a repost of Mark Smith's post from November http://community.logos.com/forums/p/4105/31611.aspx#31611
The topic navigation still has not been restored for these resources.
