I have not documented those cases. I guess usually it is a shell prompt
but I cannot say for sure it is always that. Anyway, my screen windows
are at shell prompts most of the time so this is what you would expect
(if the problem is not caused by the program running within screen).

Again, I cannot say for sure. Mostly it is beyond an SSH connection. But
again, most of my screen usage is via SSH so this would be expected even
if it is totally unrelated.

At least in the last cases the problem was not a general freeze of the
SSH connection. The other windows in the SSH screen session were responsive.

That has happened before. That's why I typed ^A-q. Should ^A^Q be any
different from that?

I forgot to mention that I tried ^A-f, too, and that it doesn't help either.
