newbie needs help: footnote numbering

[Jan-Peter Koopmann]

Hi,
 
I am writing a thesis with Lyx using the koma book class. I noticed that
the footnote numbering restarts at 1 in every chapter. I do not want
this. How can I turn this off? I looked everywhere but have to admin
that I am too blind. Please help,
 
Regards,
  JP
