If you are trying to get a window that has "disappeared" when using the  
CLEAR key, you can try going to another shell and using DISPLAY 1b 21 >/w#
where # is the window # that you know that BASIC09 is running on. I used  
to do this in earlier versions of Nitros9 (2.01 an earlier); don't know if  
it still works in the 3.x series... but it might be worth a try.
