how to make tkinter window unsizeable

[d. savitsky]

i have a very simple tkinter interface.  the code is more or less

#-----------------------
def MakeInterface():
    b = Pmw.ScrolledText(root, usehullsize=1, hull_width=400,
hull_height=300)
    b.pack(side=TOP, expand=0, padx=5, pady=5, anchor=S)


if __name__=='__main__':
    root = Tk()
    root.title('Title')
    MakeInterface()
    root.mainloop()

#------------------------

there are a few other things there, but not many.  how do i keep the user
from resizing the window (minimizing i fine).

thanks
