Editor role not properly working [solved]#

Hi All
I have a strange problem, in an new evo 1.0.5 installation. somehow the editor and publisher role are not working. In the Manager >security > content management all the check boxes are selected but when a user with this role wants to save a new resource there comes a message that there are insufficient rights to do so.
So I created a new role, but there I get the same problem. It is impossible to save new resources. it looks as only the main Administrator can save new resources.
Any idea how I could solve this problem?
evo 1.0.5
php 5.3.6
MySql 5.5.9
on MAMP 2.03

just further evaluated the problem!

When creating a resource inside a container you can save the resources. But as a soon as I want to create a resource on the root level - I get a permission denied.

There's a separate permission for that. I can't remember what it's called atm.

Thanks BobRay

yes it is. tools > configuration > user configuration

thanks for that hint.
