Now that I have DSL, I could spend some more time on diagnosting.  The
previous 3.4x repeatedly downloaded the exe's from www.httrack.com. The latest
3.42-3 did not.

Updating httrack.com only used one connection. For html and gif, ico.  Only if
I deleted the .exe's and updated did it use multiple connections.

Didn't see any.

I compared the logs and files from the two versions. 3.32 found more links.
(Took longer because of a timeout issue.)
