Mine still behaves the same way as Unkel Dale describes it.
On my screen, I can see the top portion of a photo, and if I click on it, it "zooms" in to a separate window where I can see the whole pic ("zooms" is in quotes because it doesn't actually get any larger). Clicking again closes the separate window.
Fine, but if you're just browsing, you still have to scroll down to get to the "Previous Image / Next Image" buttons...
