I tried HTTrack for a while--it works beautifully at downloading sites, but I
could never get it to download just pages from a list without it weirdly
renaming them (images worked OK, but getting pages doesn't).  I tried about 30
different programs.  None of them worked--either they also renamed files, they
wouldn't accept large lists of URLs, they had various problems with a big list
even if they took it, etc.  Since I'd had such great experience with HTTrack
up until I tried this, I was extremely frustrated that no one on the forums
could or would deign to answer questions like the one in this thread.

Here's the solution.  Website Downloader (http://www.galcott.com/wd.htm). 
It's easy, nothing to configure, it just works, and it downloads 10X faster
than HTTtrack.
