No reason to recompile the class. This is a development time/compile time setting. the compiler uses this settin to see where to pull code from during compile. Once you make the change it is immediate in the class. In other words after you make the change when you modify the class you see what your parent class is by both how VFP displays the parent class in the properties sheets as well as the right PEM's showing up or not.

Maybe someone else will chime in.
