gtk_widget_set_events (drawing_area, GTK_EXPOSURE_MASK);

Hope this helps,

(Configure events are sort of special - gdk automatically adds
GDK_STRUCTURE_MASK to the event mask so it can keep track of
window size.

Aargh. Just thought of a bug in gdk_window_set_events. Not that
it affects much - it isn't used by gtk_widget_set_events.)
