I tried to move a static method to another class.  I got the search 
results and accidentally clicked in the editor window.  The search 
results for refactoring disappeared, but I brought them back with alt-3 
and pressed "Do Refactor".  IDEA said something had changed since I 
searched and asked me whether I wanted to redo the search for references 
to the method.  I clicked "yes" and got an empty "Looking for usages..." 
dialog.  The console window contains the following exception:

java.lang.NullPointerException

Now I can't get rid of the modal dialog.  It seems I'll have to kill 
IDEA with the task manager.
