I tried several times to mirror the quite complex site 
of DESY (Hamburg, Germany: www.desy.de)within the 
limits of 4 internal and 2 external levels and no 
special filter. Every time Httrack hanged after 15 
minutes and about 850 downloaded files. Is it possible 
that there is a problem with recursive links (a link 
to the same page via other pages, perhaps even 
external)? What else could be the reason?
