Yesterday I installed SecurityKISS (free) to give it a try. The install went fine and everything seemed to work okay -- with one exception. . . every time I attempted an internet 'search' using either StartPage or Ixquick, I encountered a captcha challenge. And it wasn't a one-time thing -- it happened with every new search What's that all about? By the way, I didn't get the captcha thing when searching with Google, Yahoo or DuckDuckGo.
