[Zope] Security problem

[Punn]

Hello,

I am newbie.

My Zope security works in a strange way:
The security tab says as follows:
When the Acquire permission settings checkbox is selected
then the containing objects's permission settings are used.

It took me some time to understand, that
the settings are USED, when the Acquire permission settings checkbox is
UNchecked.
All checked settings are ignored.

For example, if I want to prevent Anonymous user seeing something,
I must uncheck in the View row  "Acquire permission setting" and "Anonymous
user" columns.

What is wrong?

Zope Version:  Zope 2.3.1 (binary release, python 1.5.2, linux2-x86)
Python Version:  1.5.2 (#10, Dec 6 1999, 12:16:27) [GCC 2.7.2.3]
System Platform:  linux2
