When I select a scrivening in one of the editors, I want to see only that scrivening in the other editor. However, sometimes all scrivenings in that folder appear separated by a line in the second editor. Sometimes, I can see one scrivening at a time, but I have not figured out what feature controls these options. Any suggestions?
This sounds a lot like the described problem in this thread. We never did figure out what was going on since the problem went away after closing and opening splits.
Seems like a bug in upgrading v2 projects—if you have a copy of the backed up original project that exhibits the problem on upgrade we could take a look at it.
