You shouldn't need to do that if you are running startxwin.bat from the 
d:\ drive and Cygwin was installed to d:\cygwin.  On the other hand, if 
you used a directory other than d:\cygwin, you would have to set 
CYGWIN_ROOT.

Short of an administrative permissions fix (which I still think should 
work), I can only suggest that maybe it is time we start trapping the 
logoff/shutdown messages and call GiveUp when this happens.  I would 
think that Windows would send the WM_QUIT or WM_CLOSE message to all 
open applications in these cases, but I could be wrong.  Are the users 
simply turning the machine completely off?  If so, then you would need 
to retrain the users before looking for other solutions.
