How can I restart/recover window list applet?

[lappin <galaxylappin optonline net>]

 am using gnome 2.2.0.1 with Redhat 9.  Starting yesterday I noticed that when 
I minimize a window it totally disappears.  I read through the help documents 
and gathered that the problem is the window list applet.  I think the applet 
may have been removed, or is no longer running.  How can I recover the 
applet's functionality? 
 
Thanks in advance for your help.  I posted this question on Red hat user list 
as well but no one seems to be going there.  I am sorry for the double post 
and it will not happen again.
