No menu item appearing for "Re-scan mountable devices" on desktop

[Tim Lewis <tlewis timelinevista com>]

Hello again,
Just like the subject says.  I have all the newest stuff installed, but
no menu selection appears.  I am running as root, and am using Redhat
5.2 with the April 14 RPMs.  How can I get this corrected?  i would like
these devices available on the desktop.
