Well, I downloaded the software from here http://www.eguidedog.net/ekho.php, the link that you furnished, Turnoi; but at first it wouldn't install-however, I did manage to install it with gdebi package installer; the trouble is now is that I can't find the installation; perhaps a command line or two will bring it to the surface when I have the inclination; it's probably all a bit advanced for me anyhow, but thank thee for replying.
