Whenever I'm visiting Super User in incognito mode, I have to verify that I'm a human (almost every time). I realize that this could be avoided by not being incognito, but for various reasons, I'm using Chrome in incognito mode as default. It works when I log in, but sometimes I just want to browse questions and answers, without having to log on. It only happens when I search, or otherwise "communicate" with the site, not when I only visit stuff on the front page.

I'm using Chrome version 40.0.2214.93 m.

I experience this on two computers, so I guess it should be reproducible for others too. Is it possible to fix this?
