Help me kill the second top leve widget without killing the first one

["Subhrangshu Supakar" <ssupakar gmail com>]

Hi All!,

    I need help again!

    In my code for a software the main window that appears at first, contains a

    tool XXXXXXXX.

    On clicking this tool it generates a graph (using GD::Graph) and displays it

    on a second window ( toplevel widget , $Window =

    Gtk2::Window->new('toplevel'))
, which provides some more tools for
    maipulating the generated graph. This window also contains an 'Quit' menu
    linked as: $HdrMenuItmQuit->signal

_connect('activate' => sub
   {Gtk2->main_quit});
   The problem is on the first click on 'Quit' button nothing happens but on
   the second click the second window as well as the first window, both
   disappears and I don't get error messege. At the same time the X button on
   the window works absolutely fine.
   cheers!
