I tried to reproduce your problem. But I was not successful in Edgy. Your problem might be fixed in Edgy.
Could you please download the Desktop CD of Edgy Knot 3 (from http://ftp.acc.umu.se/mirror/cdimage.ubuntu.com/releases/edgy/knot-3/ or another mirror), boot from it and look if the problem still persists?
