Gtk::ScrolledWindow Question

[Andrew Krause <andrew openldev org>]

By using this line of code:

   textview->scroll_to(textview->get_buffer()->get_insert(), 0);

... the ScrolledWindow scrolls to show the cursor on the screen. My 
problem is that if the ScrolledWindow contains an HBox that contains a 
TextView, the above code does not work. The vertical scrollbar flickers 
down for a fraction of a second, but returns immediately to the top of 
the buffer. Any ideas?
