gtk_window_set_modal() handles that.

The above is substantially correct. (modulo typos, or whatever, 
I just typed it in without testing). Once the widget is destroyed,
it is gone so there is no way it is going to pop up again
unless you create it again. I'd suspect something is fishy
with the code that was being used.
