Ideally you would locate the bug causing this to happen, and fix it.   
What can cause a DOS console to appear?
GDNC is a non-gui application launched as a child task ... so nothing  
should make it appear as a window ... it doesn't have one.
I suspect some bug in your code or in the windows backend for the gui  
is triggering some windows specific feature to get the subtask  
displayed in a window.
just launching gdnc separately (so it's not a child of your  
application) might prevent this from happening ... but what really  
needs to be done is identifying how/why this is caused, since  
presumably it could happen t *any* task launched as a child of the  
application.

Yes please.

You can disable the workspace notifcation center ... but that  
probably just hides this particular case of a more general bug in  
your code or in the windows backend (or possibly in the NSTask  
code) ... much better to find out the real cause and fix it.
