Limit Toolbar Access

Hi,

I am trying to limit the toolbars that a set role can access. I have restricted this in HEAT Admin, however, the users can still right click on their toolbar and see all other toolbars. They then can just add any of of our companies toolbars, despite the restrictions we have set. The image below shows a restricted role has been able to add a mangers toolbar.

Any idea?

Thanks in advance

Samantha
