Thanks for the quick reply.  Does the disable-security-limits work in 3.33.15?
-%! says invalid option
--disable-security-limits says Unknown option

the full command line option is thus:

httrack --disable-security-limits
-qi%e0C2%Ps0u1%s%uN0I0%I0p0DaK0c32T30R1H0%kf2A5000000%c20%f#f -F "Mozilla/4.5

-%l "en, en, *" <http://www.kango.com> -O "/opt/searchspark/spider/kango" -*.png
-*.gif -*.jpg -*.css -*.js -ad.doubleclick.net/* -blog.kango.com/* -%A
php3,php,php2,asp,jsp,pl,cfm,nsf,rhtml=text/html

I'd like to run without security limits against our own site in order to
precache objects. 

Thanks in advance.
