Administrator cannot edit post from frontend

Hi,

I run Easybook on my Joomla 1.5 website, but the administrators are unable to edit/delete posts from the frontend of the website when they log-in via the frontend.

I have selected Frontend-Published for editing the posts, as the (backend) Administrator role should always act as a Publisher on the frontend in Joomla. I cannot change it to Administrator for EB, as I don't want to give all Publishers admin rights on the backend. When I give one of the Administrators Publisher rights he is able to edit/delete posts (but can no longer do admin tasks...).

Any suggestions how to make this work?

Thanks in advance!
