Your solution worked. Thank you so much for your prompt assistance.
It appears that this is an issue with Elyssa installs. As I mentioned in my initial post, it is the second time this has happened. That first time, I made the 'mistake' of choosing the option of setting a root password. Going back and choosing the option of not setting a root password cleared the issue. Considering this present situation, it could be that it makes no difference whether the root password is set or not - the problem is a bug whose effect is rectified by redoing the process. Could this be the case? Anyway, next time around I may be in a better position to get by. Thanks again.
