[protege-discussion] NPE when adding superclass

I'm using Protege 3.4.1 build 357 and just got a NullPointerException when
trying to add a superclass to a class. I was using the classbrowser and
clicking on the 'add superclass' button on the superclasses section of the
panel.
Unfortunately (from a bug-fixing point of view) when I exited the
application, started it up again and tried the same thing it worked without
problems.
Regards,
Simon
