No sure, but opening the dialog before entering the main loop could be the
problem. The following modification seems to work:

import Tkinter, tkFileDialog

window = Tkinter.Tk()
txt = Tkinter.Text(window)
txt.insert(Tkinter.END, "Choose a file, then try to select me")
txt.pack()

def openFile(event=None):
    name = tkFileDialog.askopenfilename()
    txt.insert(Tkinter.END, "\nFile chosen: " + name)

txt.focus_set()
window.after_idle(openFile)
window.mainloop()
