Tiny, drop down list of page for link creation /edition lost for user 'admin'

Strange :
Using additional manager user I created they have a "list of pages" drop down list in the link properties edition popup, so it’s easy to pick up a target for the link and it’s cool.
In Evo 1.05 I can see it displays the tree with parent and child, its a really cool stuff.

But if I’m using the admin user(the very first created during the modx install) then, this drop down list does not exists

Ho can I get it?

thank you

a little up ?

I do not find this in manager manager neither.

So why do I have a drop down list of all modx doc in link edition popup (tinymce) when working as an ADMIN and not when using another role.

thank you
