Trouble maximizing windows on MS Windows

[Jared Henley <jared henley pelena com au>]

I have a Gtk application that needs windows to be maximised at their 
creation.  This is specifically because i) there's a lot of information 
in tables that needs maximisation in order to deal with sensibly, and 
ii) quite a lot of these windows are being opened (and closed) during 
normal use.  (It's a forms-based database app).  I'm using Gtk3 via Python.

So I use the Gtk.Window.maximize() method to maximise a window, and it 
works very well on native X11.  But if I run an X server on a Windows 
machine (XP and 7 tested), the window is not maximised.

I've got an installation of Gtk3 running under windows 7, so I tried 
from there too.

win = Gtk.Window()
win.show_all() # A window appears
win.maximize() # Window actually maximizes, but isn't repainted
win.connect("destroy", Gtk.main_quit)
Gtk.main() # window gets "restored"

From that little test it seems that the maximize method is actually 
doing _something_ that Windows can recognise, but I can't work out how 
to make it stick.

Does anyone have a clue about how to solve this?  I've trawled the 'net 
and this list and come up with nothing.

Jared.
