have the send_event field in all GdkEvents. gtkmenu.c, gtkacceleratortable.c, gtkwindow.c: unreference accelerator_table. gtk_object_query_args: removed seq_ids again, must have been quite tired when i commited that change ;) gtkoptionmenu.c: assure GTK_BIN()->child is empty when reparenting a menu_items child. gtkwindow.c: fixed some memory leaks. -timj
