In the latest build, the option to "Browse Mirrored 
Website" at the completion of the mirroring will fail if 
you use the random filename option ('no index.html...' 
error).

The Expert option "Use a cache for updates" seems to be by 
default checked. I wonder if that's a good choice. It 
caused me a half hour of head scratching this morning 
until I finally found it and unchecked it. I simply could 
not get a certain page to refresh even though it was 
updated on the server. Even unchecked "update hack", and 
that didn't work! Then I really started to freak out when 
hundreds of deleted .htm files would magically reappear in 
the mirror even after I had shut down the web the server. 
There was also no indication in the log that these files 
were coming from a cache. BTW, where IS the file cache???
