URGENT: Problem with GtkPaned

[Matteo Frigerio <drhammerit yahoo it>]

hello, i have a problem with GtkPaned.
The attached file is a source that reproduce the
problem (build with gtk+-2.2.3 under win32).
The problem is that when the user move the first paned
the widget in the second paned is
not redraw correctly. What can i do ? Is a bug or i am
wrong ? 
This is a small problem but the release of application
is near.
NB: In the real application the problem appear also
when i use gtk_paned_set_position(): the widget
in the paned is not visible, but if i move with the
mouse the paned the widget magically appears.



thanks, hammer.
