Hi All, I found this "bug" that appears in some of my code now, and describing it may be a little confusing. In what follows I refer to a function called "class_name()" that I use to create an instance of the class "class_name" that is defined in class_name__define.pro. I have a lot of compound object widgets where I make a function that has the same name as my compound widget class, and it returns the widget_id: id = class_name(obj=obj, etc) Here I use the keyword "obj" to get the instance of my class called "class_name" that is created in the obj_new('class_name',...) call in the widget creation function called "class_name". Now, in IDL8 when I call the widget_creation function "class_name", id=class_name(obj=obj,etc.) this is a direct call to "class_name::init" method in my class_name__define program, and if the call does not throw an error, instead of returning a widget id it returns and object reference!!! For now, my solution to deal with this is to keep the name of the widget creation function the same and change the name of the class to "class_name_class" so that my calls to the widget creation function (that are peppered throughout my applications) are left untouched and I can fix this in one place. Anyone else dealing with a similar item in IDL 8.0? -Larry
