I was going to say I can't reproduce it, but then I could.

I couldn't reproduce the problem as is, but I have screenrc that
starts a bunch of windows, so I tested with -c /dev/null and then I do
see the problem.  The second invocation doesn't start the new screen,
just as you show.  But if you wait a little bit (about 5 seconds it
would seem) after the first session is quat, then the new session is
created ok again.

[pardon my bash^Wcsh'isms, but i think it's appropriate here as it
indicates the command is repeated as-is from history and spares the
reader doing the verfication]
