Can you reproduce this?
No. I enable the mentioned option, open 3 documents (3 windows) and quit with CMD-Q. Next time I launch the application the 3 windows open again and when I quit all is fine. I have build a 2.0.0alpha1 dmg which is now placed there: http://ftp.lyx.org/pub/lyx/devel/lyx-2.0/alpha1 Perhaps you can try this one? Stephan
