The other thing that could have happened is that some error occurred.
Is there a red triangle in the upper left hand corner of the display
or an error message on the console (if you have one)? If you have a
red triangle click on it and send the results. Also if you are
willing and it is small enough send the ontology and a description of
what you tried.
