[Pharo-project] cant remove accept: method

Pharo 1.0 I have a class that has a method accept: that is no longer used. When I go to remove it, I get the message: Possible call to accept: in XXXX Browse? If you do no, it doesn't remove the method. If you do yes, you can only browse, not remove. How can I remove the method short of filing out the class, removing the method and filing the class back in?
