WTF is wrong with Pixelmator?!

If you go to Apple's app store right now, you'll see that Pixelmator won the app of the year award. That's interesting, because I have purchased this app and I can't seem to do anything useful with it.

There. I've framed my image perfectly with the cropping tool. Now, let's see how it looks when I crop it.

WTF?!
