Can't remove icon from desktop
I recently downloaded Adobe Flash player and it created an icon on my desktop. I selected "eject flash player" and the adobe icon changed to a Macintosh HD icon, and now I can't get it removed. I've already tried to drag it to the Trash but that isn't working. How can I remove get it removed, and is it some kind of duplicate of fake hard drive path that stuff will be saved to now?
