Multiple windows/dialog in one interface file.

Is it possible to have multiple windows in a glade file, and display
only one when the program starts, then show/hide the others as the
need arises ?
I can't find how...
I have a main window with a menu. One entry shows the about dialog
which is also defined in the glade file :
aboutmenu <- xmlGetWidget xml castToMenuItem "apropos1"
onActivateLeaf aboutmenu $ do
My problems are multiple :
1) how do I handle the close button that is automatically generated ?
I tried doing this ...
aboutdialog <- xmlGetWidget xml castToAboutDialog "aboutdialog1"
onDestroy aboutdialog $ do
But the Close button doesn't work, and if I close the about dialog by
the upper right cross button, it does disappear, but if I select again
the menuitem, then a tiny empty dialog opens, as if the about dialog
has been stripped out of all his inner components. And I get this line
(<interactive>:10852): Gtk-CRITICAL **: gtk_container_foreach:
assertion `GTK_IS_CONTAINER (container)' failed
I tried looking at the demos, but it doesn't help. The closest that
could have helped uses an about dialog it creates, instead of reading
from a glade file.
