My workaround is to create a folder named Backup in the Program Files/Inteset/Secure Lockdown/CircleDock/System/Settings folder and copy the Config.ini and DockItemData.ini files from the Settings folder (after configuring CircleDock) to the Backup folder. I created a RestoreCircleDock.bat file that copies (overwrites) the contents of the Backup folder to the Settings folder. I put the RestoreCircleDock.bat file in the Startup folder for the Locked Down User.
Now if the user deletes an icon on the CircleDock, simply rebooting the Laptop restores the CircleDock Configuration. Which is another iCon on the CircleDock, REBOOT.
