two ways to run CommView as a hidden process:
CommView with the "hidden" switch, i.e.:
CommView is already running, you can hide/unhide it by using the
"hot key". To hide the application, press ALT+SHIFT+h. To unhide
the application, press ALT+SHIFT+u.
you cannot completely hide any Windows application. When running in
invisible mode, one can still see the CommView process in Task
