Hi, After replacing the method of a class with an object of a class implementing the /run:with:in/ method, the context menu of the System Browser stops appearing, a debug context menu "Why you see this menu. Debug" pops up instead. After putting the original method back, the browser works again. Code: o := Interceptee new. m := Interceptee methodDict at: #method. Interceptee methodDict at: #method put: Interceptor new. o method. "Breaks context menu?" Interceptee methodDict at: #method put: m. "Browser works again" Is anyone else having this problem? Or am I doing anything wrong? Thanks -- View this message in context: http://forum.world.st/Modifying-methodDict-breaks-System-Browser-tp4799147.h...
