I am trying to capture 
<http://www.w3schools.com/css/default.asp>
and HTTrack just quits.  I have disabled the robots.txt 
rules and set browser ID to none.  I also tried  
unchecking 'Accept cookies'. 

The log file indicates...
No files purged
HTTrack Website Copier/3.31 mirror complete in 2 seconds : 
3 links scanned, 3 files written (5375 bytes overall), no 
files updated [503 bytes received at 251 bytes/sec]
(No errors, 0 warnings, 0 messages)

Suggestions are very much appreciated.
