Hi there,
Have you tried to configure keep alive in /etc/ssh/ssh_client.conf or
/etc/ssh_config -cant remember the right location now :) ?
Just set ServerAliveInterval to N to send a packet every N seconds.
I recently updated to 1.7 and the same happened to me, I use screen a
lot, and sometimes, when I came back to a session, it had died.
Just a guess but maybe ssh_config got updated.
Don't forget to restart the service.
Good luck.

Dawud.
