Sorry for my english.

I have created some category for the events.
I have set the permission for the category and anonymous user can see every category.
I also have set the permission at the group in the System Administratiton but.....

In the calendar all the events with category are hidden at the anonymous user. More: the dialog list for choise the category is also hidden for them.

I have controlled more time the setting and it seems good. What kind of control can I do?

thanks
