Humm, just finished the mirror successfully:

HTTrack mirror complete in 5 hours 36 minutes 13 seconds : 
3407 links scanned, 2265 files written (435628782 bytes 
overall) [477293026 bytes received at 23659 bytes/sec], 
1011627 bytes transfered using HTTP compression in 6 files,

The total amount of bytes on the folder is 550MB with all 
cache and logs.

Definitely, this is a GUI problem, I think (some DLL 
problem or Windows versioning problem) but I just don't 
have any idea how to detect it :(
