Resolved - Users are still able to take a screenshot by pressing 'Ctrl/Alt+PrtSc' regardless of effective access permissions for 'Screenshots' type
Users get 'Access denied' message when trying to take a screenshot with 'PrintScreen' keystroke. However, they are able to bypass this control with 'Ctrl+PrintScreen' or 'Alt+PrintScreen' keystroke combination even if they do not have sufficient 'Clipboard' - 'Screenshots' subtype access permissions.
This known problem has been resolved in version 7.1.34460.
Upgrade to the latest version of DeviceLock (7.1.34460 or higher).
