How interactive is GroundControl?
GroundControl has several different message boxes you can use. A regular Ok message box displays a custom message, and waits for someone to clear it. An Ok/Cancel message box also displays a custom message, but remembers which button the user pressed to clear it, so you can take different courses of action. Finally, an input message box will ask a custom question, and save whatever the user typed in a variable , which you can use as a parameter to any function that GroundControl has.
