Edward,

This _seems_ to work do you have an example that does not?


import Tkinter
root=Tkinter.Tk()
variable=Tkinter.StringVar()
l=Tkinter.Label(root, text='On or Off?').grid(row=0, col=0)
rb1=Tkinter. Radiobutton(root, variable=variable, value='On', text='On')
rb1.grid(row=0, col=1)
rb2=Tkinter. Radiobutton(root, variable=variable, value='Off', text='Off')
rb2.grid(row=0, col=2)
rb2.select()

root.mainloop()
