Reloading in Chrome worked (I checked with md5sum that it's the same file as before, when it didn't work), and copying out of "The" works from Chrome. Foxit Reader doesn't work, no matter how "The" is copied.
(Both you and Luke didn't name their readers where copying works, which is unhelpful if you're mentioning the fact that it works somewhere at all.)
Copy-paste works for me in Adobe Acrobat Pro 9 and in Chrome.

Note the new publication design. We are currently porting our earlier publications to this template, too.
