What causes "The Finder can't quit because some operations are still in progress" error message? I am receiving this message when I'm trying to shut down my computer and I don't have any Finder windows open. What could be causing this message and how do I fix it so that I don't have to perform a hard shutdown?
Here's another way to Force Quit an application:


Click the Apple Menu 
Hold Shift, and notice that the 'Force Quit...'
menu item has changed to 'Force Quit [frontmost app name].' 
Select 'Force Quit [frontmost app name]' to force quit the Application.
