User Comments:
MackSix: 1. Installed FindBugs.
2. Configured to use single inspection. (Class implements Cloneable but does not define clone() method)
3. Clicked OK
4. Opened up Configuration again and the list dialog box was collapsed smaller and the list was cut off on the left side.
5. expanded dialog box out and moved partition over until full list showed in dialog box.
6. Click on Bad Practice node to close it.
This NPE happned.

Also, the single inspection fails to find problem in file, but running the full FindBugs configuration on the file is successful in finding it.
