(ROSE) invisible parent to a class

[\(WinExpert\)]

Hello to everyone on the list,   We have a class that is supposed to be basically an interface class. It holds no dependencies on other classes and is really meant to just be used  as a standalone class.   However when I view the specificiation of the class and look at operations,   it has several parent classes.   I cannot figure out where some of the parent classes are coming from.   They are not supposed to be there.  I cannot find the diagrams that would suggest this class is a child class via specialization (is a) of any of the other classes.   How  can I determine where/what is making this relationship?   I tried Show Usage but that didn't help.   Is there a tool i can run that shows where this class is getting the information that it is a child of another class?   Thanks   David Stockwell
