It looks fine to me.

If you have created more than one Tk(), then the IntVar may be in a
different interpreter than the checkbutton (for instance, by adding the
following two lines above 'root = Tk()'
    not_root = Tk()
    not_root.wm_withdraw()
I can get the behavior your describe)

You can make sure your variable is in the right interpreter by using
<         self.var = IntVar(master) 
just as you do for widgets.  That change makes your script work whether or
not 'non_root' was created at startup.
