In your program, every time you create a frame, you create it like that:
frm = Frame(root=Tk())
This creates a new Tk interpreter and a new main window each time it's
executed. So the two lines:
> outputRollerWindow = OutputRollerFrame(root=Tk())
> paperMotorWindow = PaperMotorFrame(root=Tk())
in the __init__ of ListModule are certainly not what you want to do.
If you want to open a window when the user clicks a button, I'd advise you
to begin with a far simpler example to get the mechanism right. A simple
button opening a window containing only a label would be a good start. The
code you included is too complicated to guess what you're trying to do
exactly. It will be easier to explain what's wrong on a smaller example...
