When I do a large transfer with httrack, there's a little 
cosmetic bug in the error report - total file size is shown 
as a negative number.  An example:

HTTrack mirror complete in 2 hours 51 minutes 35 seconds : 
3600 links scanned, 3594 files written (-486703801 bytes 
overall) [-487438978 bytes received at 369842 bytes/sec], 
4.0 requests per connection
(No errors, 2 warnings, 3584 messages)

The total size of the download is actually 3.55GB (about 
3,815,000,000 bytes) so it's presumably wrapping at some 
number such as 2GB.  Version being used is 3.23 on WinXP 
(and a quite fast cable modem).

It's a really great program to be able to do all this in 
one download without any problems! Just letting you know so 
that perhaps the size of the counter for bytes received can 
be enlarged in a future version, as downloads are getting 
larger nowadays.
