Hello,
 I humbly take back my bug report.  It appears that the problem was
triggered by a Unix style path in my .emacs file.  I got the scoring working

 I really tried many things before sending the report (including xemacs -q),
but got confused in the end.  Too much coffee.
 Sorry for bothering you.
 Cheers,
 Marcin
