I don't know if this has been reported, and I'm not even certain this is the problem, but I strongly suspect it.
Many time I have opened and closed Logos 4 and it maintained the resources I had opened, from session to session. Recently I decided that I wanted to check my reading plan each startup, so I clicked "Show home page at startup", something I had not previously checked. The next time I opened Logos 4, all of my resources (painstakenly opened and sorted) were closed!
I opened a few, and resumed my work. I closed Logos 4 (this is Rev 13a) then reopened it a short time later to the Home Screen. My resources were again closed.
This is annoying if it is a bug, but much worse if it is a feature.

Steve
