[Tutor] Is this me or is it something odd in tkInter?

[David Maclagan]

I'm trying to use some of the prepackaged dialogs that tkinter comes 
with, specifically askopenfile in tkFileDialog.py, and get the following 
error:

    self.tk.call(
TclError: can't invoke "frame" command:  application has been 
destroyed
-------------------

The program that's generating this is:
(well, okay, there was originally more to it, but I hacked it back to 
the smallest I could, and still got the same problem.)

-----------
from Tkinter import *
import tkFileDialog

root=Tk()

def openfile():
    filename = tkFileDialog.askopenfilename()

menubar = Menu(root)

filemenu = Menu(menubar, tearoff=0)
filemenu.add_command(label="Open", command = openfile())
# display the menu
root.config(menu=menubar)

frame = Frame(root)

frame.pack()

root.mainloop()
--------------------

Am I making a (or some) fundamental error(s)?

I'm using IDLE 0.4, and python 1.5.2 on a win98 system
