I'd like to suggest a little change in the behaviour 
of Winhttrack based on my experiences with Teleport 
Pro. When Winhttrack finishes its job, it lets you 
browse the-just-mirrored site. But when you click the 
button it starts to open mirrores website in the last 
opend windows e.g. of Internet Explorer. In the same 
situation Teleport Pro when asked to Open the site, it 
opens the site in A NEW WINDOW OF BROWSER. I think it 
would be more convenient for user if Winhtrrack opened 
mirrored websites in a new window.
