No. #lightbox: is like #call:. It does a full refresh to the server
and generates a completely new page with the background and lightbox
HTML. The only difference between #call: and #lightbox: is that call
does not render the parent component, #lightbox: does to make it shine
through using some CSS effects. You can easily observe that in
FireBug.

Now of course there are nicer ways to do a lightbox, e.g. by loading
the dialog using an AJAX call. However this does not work as part of a
flow and requires you to write and adapt some Javascript code to work
with your page layout.
