I am observing something strange, what previously I never observed. I am logging over Ethernet into other computer, and with C-a C-d I put screen in background, then I log off, and when I log in again, screen cannot be resumed, and I can verify that t is not any more in memory.
Is that known bug from the old version or something? Screen version 4.05.01 (GNU) 25-Feb-17 Jean
