Today I was studying Prov. 18:1. When the passage guide populated, I selected the Bible Knowledge Commentary. It opened to Prov. 18:1. Great! Hit <right arrow> to go to next parallel resource, USB Handbook, Prov. 18:1. So far, so good. Same for Word Commentary. Next <right arrow> goes to NAC. Section is Prov. 17:27-18:4. Okay. Same for next two. Finally, <right arrow> to Derek Kidner's commentary on Proverbs. Same section is shown (Prov. 17:27-18:4), however there is an entry for Prov. 18:1, the verse I'm really interested in.
It appears the Parallel resource is getting it's reference from the currently displayed verse (or range) rather than the original entry. It is annoying to have to keep entering the original reference when the software thinks it knows better. 
And while I'm on the subject; I've noticed since Logos 7, that the focus seems to get lost easily. I click the right arrow to advance to the next Parallel resource. It works some of the time, and some of the time it does not and I have to re-click inside the resource to get the focus back.
Thanks for listening.
