Hello, When I delete a class, a window pop to inform me that some methods use this class. So I remove the methods because they are not usefull without my class to removed.
But when I close the window, the methods stay on the Browser, so I remove this methods on the Browser. Then, I remove an other class and "BOOM" an error appears, the key which represents my class is not present in the SystemDictionnary (it's normal), but I can find the key in the RPackage metaclasses.
