Don't know whether this is a netscape or a gnome bug, but if
you click on the buttonbar from the bottom right hand corner
of communicator to turn it into a window, you get an entry
in the pager winlist. So far, so good.
Minimising this window sends the window back to the
buttonbar, but it's entry still appears on the pager.
This seems to be an enlightenment/gnome-pager bug. I will
forward it to the GNOME mailing lists.
