Hi Xavier,

I think, I have done it analogues to  your sample:

In the textbox, where the base URLs are given, added "-%S 
rules.txt" in the same line.
After pressing "Finish" (it is actually "Fertigstellen" 
because of the german  Windows :-)). 
Immediately the page "Site mirroring finished" appears with 
an error message:

-------------------
A problem occured during the mirroring operation
""
During:
<<long and cryptic Command Line - "-%S rules.txt" appears 
in front of -O parameter>>
See the log if necessary.

Click FINISH to quit WinHTTrack Website Copier.

Thanks for using WinHTTrack!
--------------------

There is no further logfile. Only thing different is, that 
the existing doit.log file is empty. I think WinHTTrack is 
trying to build a new one.
I am not sure about the location and the internal structure 
of the rules.txt file.

Thanks

Juergen
