You should claim your money back -- keeping the hardware, of course. ;-

Actually, I've never burned a CD under Linux. In fact, the only CD 
burner I possess lives in a BeOS-only machine that has been terribly 
unstable for quite some time. :-(
Maybe I could try the Knoppix CD I got recently. I don't know whether 
there's a CD burner app on it that supports burning multisession 
ISO9660 CD, though. Oh, I've got a better idea, I could ask stippi to 
burn some CDs for me under FreeBSD. :-)

Cool. :-)
Hint for the Linux user: Try a newer distribution, or build your own 
kernel. ;-))

If there indeed exists a newer standard, it would be nice to learn 
about it. :-P

It's progressing slowly. After some painful attempts to build a GUI 
with the plain Interface Kit, I decided to write some classes for a 
generic layout management. Don't worry, I don't intend to hold myself 
off too long with that. It will be relatively simple, and by accident I 
have this very powerful, `almost complete' layout library of mine 
discontinued some four years ago, from which I can borrow some ideas 
and code.
