This new version, 3.21-7 has made it so my command line 
version with an httrackrc file doens't work again...  
Better inspect that.

httrackrc file
--------------

set path "C:\poo"
set list "C:\Program Files\WinHTTrack\url.txt"
set near on
deny *
allow *.gif
allow *.jpg
allow *.css
allow *.js
allow *.png

url.txt
-------------
<http://www.osha.gov/SLTC/eyeandface_etool/index.html>

httrack test
Unable to create log file c:\poo\hts-log.txt

Doesn't create directory either.

I'm running Windows XP Professional under an administrator 
account.
