You're close; instead of these, do the hide() in a handler for
'delete-event' and returning TRUE.
Delete is fired when the window is being removed due to user action
(clicking Ok or Cancel, or [x]ing the Dialog, or...). You already
figured out hide()ing rather than letting the Window be destroyed, but
you need to block the 'delete-event' or that's exactly what will happen.
Thus return TRUE so that it doesn't propagate further.
Hiding in a delete handler is a fairly common usage in GTK apps.
Of course, whatever code is raising the Dialog (or whatever) will need
to present() the Window to get it back on the screen the next time Help
is activated.
