Re: GtkTable isn't updating properly

Well, calling gdk_window_invalidate_rect doesn't appear to be helping. gtk_widget_queue_draw and gtk_widget_queue_resize didn't help either, applied either to the table or to its parent. This is a darn bizarre bug, especially since it now appears not to occur on Linux, only Windows.

New problem: I'm trying to put a GtkButton in one column of this GtkTable. But it isn't showing up properly, or properly calling its "clicked" handler.

I'm using gtk_button_new_with_label("Button");, but the button shows up without a label and only about 1 space wide.
