Thank you very much, Harry and UnderScore; it happens to be a problem with the nero, i removed the 6.0.0.15 and rolled back to 5 and everything went fine. Now i'm the proud user of Knoppix 3.9. ))))))

You were just right, it fitted in; the problem was the lame nero.

Thanks again; now i'll try to learn about my new OS; but don't worry; i'll be back with more stupid questions as soon as i get stuck.

C'ya
