Blocks appear in "Add a block" to users without Content Access

Hi all,

I have 2 versions of Homebox:

• one is 6.x-2.1 (production site)
• and the other is 6.x-3.0-beta5 (test site)

On the old version, the Toggle Items command shows a list of blocks that takes into account the Content Access restrictions of the current user (as would be expected).
On the new version, everyone seems to have the same list of blocks in the Add a block button. When I click on a block the user does not have access to, nothing happens.
Maybe a regression?
BTW I'm using Drupal Commons.

Going on line on Thursday...

Thanks, Francis
