Using the "M" key from Mythwelcome, nothing happens when I select the Shutdown Now option. (Mythwelcome reports that system is idle and nothing is due to record for at least 30 minutes)

In mythwelcome --setup, the Command to Shutdown;
sudo shutdown -h now

When I select the Exit (from Mythwelcome 'M" popup dialog), I return to terminal; It seems like the shutdown command syntax is wrong:

sh-3.00$ mythwelcome
