Tkinter checkbox problem on Windows 2000

[Tom Good]

Hello,

The following test program works for me on Linux: it displays a window
containing a check box with the label "test".  When I run on Windows
2000, a window appears containing only the text label.  No check box
is visible.  What is going on?  Any help would be appreciated.

Tom



My configuration is:

Microsoft Windows 2000 [Version 5.00.2195]
ActivePython 2.1, build 210
ActiveTcl-8.3.3.8330

The program:
#---------------------

from Tkinter import *

root = Tk()
checkbox = Checkbutton(root, text="test")
checkbox.pack()
root.mainloop()

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