[Updated 2013-05-21 @8:38 AM: I removed the paragraphs and image regarding a low resolution icon for Adobe Reader. What I had witnessed was, I have discovered, yet another bug in Apple's Finder application. I've witnessed the exact same phenomenon with other newly installed apps. Refreshing or relaunching the Finder removes the problem. Not good Apple! Apologies to Adobe.]
