Treatment of a window - configuration

I am using Windows 7 Tablet pc input panel under the restricted site kiosk user. I am trying to restrict the access to the tools, options window. The option window continues to open even with "close window immediately" selected on the treatment of a window configuration. The Sitekiosk warning window opens with a “‘for security reasons this action is not allowed”. Within a few seconds the security window closes and the restricted user is still able to make option changes to the Tablet pc input panel. I am running Sitekiosk version 8.6.1251. Any insight would be appreciated.
