task bar
 

hi,
i am using redhat. and some how my task bar is not appearing in the bottom
of the desktops how can i get it back.

You can right-click on the top panel and select "New Panel". A new empty panel will appear at the bottom, then you have to add objects. Right-click on the bottom panel and select "Add to Panel". Tipically you will put:
Show Desktop,
Window List,
Workspace Switcher,
Trash.
