I just tried to open Spotify's app through the OSX LaunchPad, and when I clicked on the icon, it is stuck on my screen. I've attached some screenshots to show you. I don't know how to get it down. No matter what I do to the screen, the icon is always stuck "on top" of it.
How do I make this go away? If you're curious, Spotify opened on the second attempt. The first attempt it just got stuck.
