The first image is the full pop-up window you get when you click on the TweetDeck upgrade link from within the TweetDeck desktop app. Note how the window is not sized well for the content. Not even nearly.
The second image is what happens if you try to resize the window. Granted, part of the problem may be OS X Lion's lack of window chrome (boo, in of itself), or that this is an Adobe AIR app. But did nobody test this? Especially ironic is that this makes it really difficult for the user to GET YOUR PRODUCT.
