How can I prevent the script from opening a window if it already exists?

I have a script that opens a new window with a keypad for numeric entry. Users at the kiosk keep clicking on the window behind the keypad (hiding it) and then the script creates a new one each time that it is run.

You need to give the new window a name - so you can check if it's already open, by using the WindowNames() function.
