Modal Problem with Top window menu interaction

I have implemented a modal dialog that seems to work as far as not allowing interaction with buttons or other items on the main window of the program but it does allow interaction with the main window menu and minimize/maximize/close buttons. Here is my code:

Code:

   gtk_builder_add_from_file (builder, whichdialog, NULL);
   dialog = GTK_WIDGET (gtk_builder_get_object (builder, cObjectname));
   g_object_unref (G_OBJECT (builder));
       gtk_window_set_transient_for(GTK_WINDOW (dialog), GTK_WINDOW (window));
   gtk_window_set_destroy_with_parent (GTK_WINDOW (dialog), TRUE);
   gtk_window_set_keep_above(GTK_WINDOW (dialog), TRUE);
   
   gtk_window_set_position(GTK_WINDOW (dialog), GTK_WIN_POS_CENTER_ON_PARENT);

   gtk_window_set_modal(GTK_WINDOW(dialog), TRUE);
      gtk_widget_show_all (dialog);
      gtk_dialog_run (GTK_DIALOG (dialog));
   
      gtk_widget_destroy (dialog);

I'm using GTK+ 3, C, Ubuntu 12.04.
Am I doing something wrong or is this normal behavior?
Thanks

Well from doing an exhaustive search on the internet, I couldn't come up with anything, except from someone who had the similar problem almost a year ago. I think it might have something to do with Ubuntu/Unity so I just created a menu object and disabled the one menu item that would cause a problem, and I'm now moving on.

The Minimise/Maximise/Close buttons are meant to be still available even if the dialog is modal. The menu is a different matter. Yes, this is an Ubuntu/Unity thing as a result of relocating the menu bar to a unified location. It's not specific to GTK; you can even see some of the oddities of the behaviour in firefox, etc. I would probably avoid manually disabling the menu items as this could cause problems when used in non-Unity systems. If this does make your code buggy then there's not much you can do and disabling's probably your best option; though I'd also report it as a bug in Unity and don't let them railroad you with "it's not a bug it's a quirk" arguments.

Thanks for your answer. I think as long as I handle disabling then re-enabling the menu when necessary it should work on all systems.
