Hello,

Is there a way to verify that the graphics window associated with a
given ID number is still open and valid?

You can use the Window_State keyword for the Device procedure, as
follows:

Device, Window__State = wStatus ;wStatus is an array containing the
state of all windows
isOpen = wStatus[wID] ;returns a '1' if window
identifier is open, 0 otherwise.
