[RTTY] Typo in N1MM Receive window 1

[Ktfrog007 at aol.com]

Hi,
 
I am currently porting all my ham radio software to a new computer - quite  
a job.
 
I made a small error which isn't fatal but is an annoyance and offends my  
sensibilities.
 
While setting up N1MM for RTTY I was activating my first receive  only 
screen, Rx Window 1, I typed in the MMTTY address instead of browsing  for it 
and made a typo.  
 
Now that window will never re-open so I can fix it.  I went on and  made an 
Rx 2 window properly, but I'd like to clean up the little mess I made,  but 
I don't know how to get back into the Rx 1 window.
 
Any ideas?  I'm hoping for help here rather than joining any more  groups.
