[SOLVED, for now]Replace Joomla article manager

On a test-site I installed FLEXIcontent in a site with content. When I imported the Joomla content, the Joomla article manager was replaced by the FLEXI manager.
On my production site I installed FLEXIcontent (and access)directly in an empty Joomla set-up. Now the Jooml article manager is still available and a FLEXIcontent menu-item was added to the administrator menubar.
The fact that the Jooml aarticle manager is still available is very confusing. How can I get rid of it?

hello
in joomla plugin manager
plugin systeme flexicontent
you can selected witch user are redirected automaticly on flexicontent
regards

Ah, I thought I would set a minimum user. So, when I choose Administtator it would redirect the Super Admin too. But I had to set it to Super Admin, to make it work. Strange. But I got it working, thanks .

cool
edit you first post and add [solved]
thanks

Well, it's not actually solved . I should post is a a feature request I presume. It is a flaw in the design I think that only for one type of admin user the article manager can be replaced.
