the "computer" icon disappeared, what happened?

I have openSUSE 11. There used to be a Computer icon at the lower left corner of the screen. I click on this to open up Yast, and so forth. Now, it has disappeared.

Does anyone know the easy way to put it back? Thanks.

Using gnome, you can go to COMPUTER > MORE APPLICATIONS and select GNOME CONFIGURATION EDITOR > APPS > NAUTILUS > DESKTOP. Make sure it is checked there. If that doesn’t fix it, I don’t have any ideas.
