Where'd you go Mr Listener Window?

[Mark Fasciano <fasciano@cs.uchicago.edu>]

Usually when I close the listener window, a new one comes back.  But
sometimes I close it by mistake while an expression is being evaluated,
and then the listener window doesn't come back.

Does anyone know a way to reincarnate the listener window when this
happens?

Thanks.
