Xavier,

Is the command line for the robots setting -sN[value] 
(e.g. -sN0) or -s[value] (e.g. -s0). The manual seems to 
say it is -sN[value] but I have modified the values via the 
GUI (for the Windows version) the log files indicate that 
the robots setting command line parameter is -s[value].

Regards
David
