Clicking on the far right of the "Next >>" glossy button in the penultimate page of either Programs or Samples clicks the "<<" button on the next page too, so you stay on the same page and can't reach the next unless you click a lefter click than before.
I'm trying to reproduce this, and can't. What platform are you on? Could you attach a screenshot of exactly where you're clicking, maybe?
I'm running Ubuntu 10.10, with $ shoes -v
shoes policeman (0.r1541) [x86_64-linux Ruby1.9.1]
It fails if I click anywhere on the right half of the 'next' button (where it overlaps with the next page's 'back' button). For instance, here.
Strange. This doesn't happen on OSX.
I can confirm this behavior on Ubuntu 11.04 virtualbox VM, on OSX 32-bit intel host
