Workbook access rights different in Fusion/Classic client

 Hi, when managing as an administrator the workbook access rights for the users of a domain, I notice a difference between Classic and Fusion Client.

I wish to let a user access only some workbooks belonging to a workbook group: therefore in the Security Administration Workbook I select the "Denied" option for the specific user/workbooks.

The effect is:

- in the Classic Client: the user can see only the workbooks he is allowed to see (he can't see the denied workbooks)

- in the Fusion Client: the user can see also the denied workbooks, but he can't enter them ( they are grey-colored )
