>You were on the right track using two instances of the class browser. What the documentation doesn't clearly state is that to drag and drop you need to select the class (single mouse click) and its icon will appear in the upper left section of the class browser. Drag this icon to the other class browser and the class will copy. HTH

I just (fox)wish one could drag the class name or an icon next to it, and not have to search for the icon in the upper left section and then drag that. It's so counterintuitive.
