Center lower panel?

[David]

I have created a 2nd panel that is 'Launcher count sized to fit' that
contains 6 'launchers' that I have placed at the bottom of the screen.
But I can not seem to get it to 'center justify'. The Help says that
placing it on the right, left, or bottom should automatically center it.

What am I doing incorrectly and where can I find the necessary
information to correct this?
