restore size/position of gtk window

[Allin Cottrell <cottrell wfu edu>]

I posted on this topic a few days ago and didn't get a response. 
Now I'm trying a more specific variant of my question after doing 
some testing.

What I'd like is for my gtk app to "remember" the size and position 
of its main window from one session to another (at least as an 
option).

I have tried attaching a callback to "configure_event" on the main 
window, which enables me to record x and y position plus width and 
height.  In its simplest form, this does not work properly (as is 
suggested in the GTK docs): restoration of the main window is 
subject to "creep," which can result in crucial elements of the main 
window going off-screen or under the taskbar.

On linux (more specifically, with Sawfish as window manager) I can 
fix that by taking the main window's x and y position from the 
function

gdk_window_get_root_origin()

This eliminates the creep.  But so far I have found nothing that 
fixes window creep on win32.  If a user maximizes my app's main 
window, then despite my best efforts, when we attempt to restore the 
maximized main window on startup it is offset relative to the screen 
such there's a margin of exposed desktop at the top and crucial 
stuff goes under the Windows taskbar.

Is there any known fix for this?
