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?

I don't know about typing Ctrl-A twice, but Ctrl-a A should give a prompt to enter a new title for the current window. You might want to try Ctrl-q then Ctrl-d a couple of times until you see
[Screen is terminating]. If you get that, then nothing has frozen, it was just waiting for input somewhere. What does your~/.screenrcfile look like, if you have one?
