Removing "edit primary links"

I am using Drupal-4.7.2 and the default theme (pretty much default everything). I want to remove the "edit primary links" menu item on the top right.

After searching through the forums I learnt that in earlier versions that was handled in the theme configuration section. However now I have to use the menu configuration.

So I head to the menu section, I see something like this

Primary Links
* edit
* delete
* add items
--------------------------------------------
Menu items Expanded Operations
------------------------------------------

So I add something and it shows up on my top right corner.

I am still trying to find a way to delete it however. Some people have suggested editing the configuration files (CSS, the theme file or whatever) but I want to resort to that only in the last stage.

http://drupal.org/node/63601 says "..................check to make sure the option on this page hasn't been changed to "No Primary Links".
I don't see such an option at all (maybe the documentation is wrong? Someone needs to change it?). In fact this is the option I think I really need.

http://drupal.org/node/57367 reveals some interesting information, but nothing seems valid for 4.7.2

Any suggestions?
