It does. Select/highlight one of the "outlook.exe" process and then select
the end process button down at the bottom. This will inform the operating
system to force close the application. Now one of two things will happen,
both "outlook.exe" will be removed from the list or the Outlook window will
be displayed.
Outside of that, I can't be of more help because I have no idea what your
computer has installed on it. I just know there are 3rd party applications
(e.g. Fax, PDA Software, .etc) that can interfere with Outlook shutting down
right.
