John,

I already have the Activatable property set.  I went to the demo to see
what I could find and there was an example there and heres the code.....

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 //FIXME: Finish implementing this function, I don't know
 //       why it doesn't work.
 private void ItemToggled (object o, ToggledArgs args)
 {
     Gtk.TreeIter iter;
     if (store.GetIterFromString(out iter, args.Path))
     {
         bool val = (bool) store.GetValue(iter, 0);
         Console.WriteLine("toggled {0} with value {1}",
args.Path, val);
         
         store.SetValue(iter, 0, !val);
     }
 }
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

As you can see the code logic is the same as mine just cleaner.  
Do you have any other suggestions?   

Thanks,

Joe
