Hey there,

Intermittently, I have been experiencing a strange problem with screen locking up

Most of the times I find a screen 'locked up' it turns out to be a
flow-control problem.  Some how, a CTRL-S (xoff) has been sent to the
terminal, given the proximity of the S key to the A key (at least on a
QWERTY layout), I can see how a quick fat-fingering might cause this
to occur.  Since I rarely do things over a 2400 bps dial-up any more,
I try and turn flow-control off as much as I can (defflow off in my
.screenrc and the first around of windows opened in the .screenrc have a
-fn in their call), but sometimes things still get stuck.  Before I give
up completely, I try a '^A : xon' or a cycle between '^A : xoff' then
another '^A : xon' and that usually frees things up, but sometimes, it's
just lost and there's nothing I have found to make it go again.
