New York Times Paywall is only for Windows?

Ok, I have recent run across quite the oddity. There are a bunch of links to the New York Times Website on Hacker News lately (thanks donohoe) and whenever I try and click on them on my windows laptop (chrome) I get stopped by a paywall login thing. However, when I try this with my Ubuntu Netbook, It just opens up articles without bothering to make me sign up. Anybody have an explanation for this odd behavior or notice it also?
