If I assign 'Current Reporter' to any permission scheme instance for any project, every other login can see that the project exists. The other 'unauthorised' views do not show issues, just that the project exists.

I am trying to have one project setup to have many clients access it - current reporter set against 'Browse Projects' works well i.e. the clients logging into this project can only see the issues attributable to them. The problem is that users belonging to groups within entirely different project can see that this first project exists ... don't want that to happen ... different product set.
