[Cooker] screen software doesn't work in M6.1

[Atif]

Has anyone been able to run screen successfully under M6.1 or Cooker?
It starts up find then I detach it and can never re-attach it.
Whenever I type "screen -r" to resume my screen session it starts
a new one.  This is rather odd and highly inconvenient.  Does anybody
know of a fix?

Thanks.
