Method for requiring Password to Exit the Application

[scott.clark]

Advanced HMI v3.99a

Any suggestions on how I can require the operator to enter a numeric password to exit the AdvancedHMI application? 

Also, how can I prevent them from dragging the form?  Ultimately, I am wanting to prevent them from getting to the PC.

Thanks,
Scott
