This happens to me once every couple of hours. When I use the screen command and attempt to switch between windows by pressing ctrl+shift+a twice in succession, my session freezes.
This has happened to me when I've used putty to ssh to cloud servers and also to servers in my LAN at home.
Does anyone know any fixes to this?
~/.screenrc
? C-A C-A should have no effect, by default. Note, I'm following screen's convention of writing "ctrl+shift+a" asC-A
Ctrl + A
and this is locking it.
