Tkinter dialog boxes

[Tony Evreshed]

I've been using the tkMessageBox in Python to create small dialogs to
instruct the user in what to do next, and I've noticed that the boxed are
alays 'on top' of the screen - that is, it's not possible to cover them with
another window.
Is there any way to do this with dialogs created in this way?
If not, how should I create dialogs that correspond to the askyesno and
showinfo dialogs but can also have other windows in top of them?

(Using Python 2.2, if it helps)


many thanks,
