Hi Olivier,

you probably want a dialog window that grabs all events:

    top = Toplevel()
    top.transient(rootwindow)
    top.grab_set()
    Label(top, text="Computing, please wait...").pack()

The call to transient() makes the dialog always stay on top of the application's root window,
grab_set() prevents any events from being delivered to other windows in your app.

I hope this helps

Michael
