I can't experiment at the moment to figure this out, but I'm
curious what you see when you turn on screen's logging. Anything
informative perhaps?
Aside from tweaking screen until it obeys, you might try the nohup
utility. I think it is much kinder to your redirections and allows
the command to continue after the shell exits. You won't be able
to re-open a tty to manipulate it, but I didn't get the impression
that was important. Between the output files and ps||top, you
should be able to see its progress well enough with nohup.
