I use Task Scheduler for NT running five command line 
files on daily basis with interval of 30 minutes, but 
three of them won't close after the download (I can 
see them running in Task Manager), this caused 100% 
usage of CPU, low of virtual memory, Dr. Watson 
warning, etc.  Is there a way that I can make HTTrack 
to be automatically disconnected after the download in 
the command line?  Thanks.
