I have been using httrack for a while (ver. 3.32-2). Today 
I noticed the following: when I click on "Next" from start 
dialog, and then "Back" and again "Next", the "Back" button 
becomes disabled, and I can click on "Next" without any 
project name.

Other things are more "cosmetical":) - status bar messages 
are not translated in language packs and the "Save 
changes..." dialog is also not translated. 

Otherwise, I am very satisfied with that tool. Keep on 
going!
