Newbie question: Gnome desktop

[Christian Convey]

Hi guys,

Whenever I've used Ubuntu in the past, including Ubuntu 9.04, there
has been a task bar at the bottom of the screen, showing each running
window.  This is in addition to the bar at the top of the screen
containing the launch menu, the system time, etc.

However, in Ubuntu Studio 9.04, the bar at the bottom of the screen is
absent.  Google wasn't any help in figure out how to make it appear.
Any suggestions?

Thanks,
Christian
