Dear Heather, part of what you are going to do is already present with my "CustomChoose"-Demos that show functionally equivalent solutions with an old style dialog and NavServices preCarbon and Carbon. In my latest announcement to this list (Wednesday 24.April, message #30824) I already discussed some peculiarities with the Carbon solution under OS 9.x, OSX-Classic and OSX native. You may download the "CustomChoose-Demo"-Combo from the DropBox. Best, Herbie ************************ Munich/Bavaria
