I don't see why you'd need Turn Flash : this is an Internet Explorer only
add-on.
You have to disable robot.txt rules but I doubt this is why the system hangs.
You may also have to change browser ID.
But as the webmaster doesn't want the site to be copied, set limits and set
scan rules to exclude the folders you don't need :
-*/admin/*
-*/attachments/*
-*/include/*
-*/ipdata/*
-*/templates/*
-*/plugins/*
