In the last week or so I noticed this box on my desktop. I can click on it and hold to drag it around, when I hover the mouse over the colored boxes the mouse cursor turns into a hyperlink hand icon, but clicking does nothing. When I hover the mouse over the triangle icon in the corner the mouse cursor turns into a four-directional arrow icon but also doesn't do anything. I can't resize it, when I click on it the the program name at the top left of the screen doesn't change, and I can't get rid of it. It stays visible on top of other programs. Right-clicking or Ctrl-clicking on it does nothing. I've rebooted and it comes right back. I've killed all open programs in the dock and it doesn't go away. I haven't downloaded anything recently that I can remember. I've tried looking through the Activity Monitor "My Processes" list but can't find anything that would seem to be it.
Help! I throw myself on the mercy of the court!
