Thanks for your prompt reply, but what happens now, or what can I do
to

upgrade.

I am not carrying any additional software or additions,
Flight Gear I have not even

heard of it before.

I am relatively new
to Linux but have been involved with computers since mid 1975.

I am
just totally confused st the moment.

Thanks Again for your reply.

Alan

Bring back DOS all is forgiven!!
