>Ok, it's a misunderstanding. If I click on the downarrows in the circle (Expand/Collapse this section), I get what I expected to get. But I clicked on the word Links (Update the list of favorite links) and that brings me to the Account Setup page where I can indeed update the list.

Yes, I enabled the images of some of them to provide a rapid access to the account setup, for exemple, which is the case here. But, the links under should work ok.
