I redownloaded Ktorrent from Ubuntu is that all that is needed to obtain the fix ? Or do I need other instructions for this.

Thank you for the help. I am sorry but I still have a question.
I run Ubuntu not Kubuntu. Will this mean that my system will
not benefit from the fix. ? - Here is my version from the ABOUT menu.

You are using Ubuntu 9.10
- the Karmic Koala - released in October 2009 and supported
until April 2011.

I guess I am new to the UBUNTU community. I understand Linux only because
I'm
and old DOS / Unix guy and hate Microsoft software. If you want to call it
software.

To me Ubuntu is about freedom. But also about real people. I take my hat
off to
people like yourself that form the very best the Ubuntu offers. Take care,
and happy "Ubuntu-ing" - * Perhaps the best Linux in the world.*
