Version: 1.4.2 (using KDE KDE 3.4.2) When editing a class diagram and right-clicking on a class and select "refactor", a child window pops up with a list of the class' properties. If the user right-clicks on the "attributes" or "operations" category, a menu pops out which offers the option to add attribute/operation. If the user clicks on that option, nothing happens.
Bug reproduced on 4.2.4. It works in current trunk :-)
It works in 4.3 too
