Using Logos 8.10 beta 3 on WIndows 10 Pro
Hi Chris
This would be better in the Beta forum.
Viewing NIV84 turned on 3 columns, turned them off, closed NIV (or used parallel resources to go to a different Bible in the same tab), then re-opened NIV and the text is in 3 columns again.
I can't reproduce. So provide details of the other two multi-resources you turned on.
