Thanks, Hal!
DW is indeed Disk Warrior, used to rebuild directory. I have a hunch that just running Disk Utility may not do the trick.
To relaunch Finder, press command(Apple)-Option-Escape, in the dialog box click on Finder, then click on "relaunch" at the bottom of the window. It helped me when icons on the desktop became unresponsive or were not rendered right (generic icons instead of application-specific).
