I cannot save security parameters in document properties

[#1]

Hello everyone,

I want to unchecked "Allow Access to properties (Users)" so users in Access Point cannot change the graphs and so on...

But each time I do it and click on "Apply" and then close the window, when I reopen it, the changes i've made are not saved...

I really don't get why. I tried to do it with all the checkboxes : unchecked them and "apply" the changes, but it never works.

I guess there must be others parameters somewhere else ?

Any ideas ?

Thanks a lot
