I must provide my own code to highlight the button. I normally keep around a small library of routines that I call often. I'll post them in a following posting. This is actually very trivial. Create a UserItem in the Dialog with the same ItemRect as the default button, and use SetDItem to set it to have a user item proc of a outline drawing routine. > (Clue that this is difficult: so many applications simply neglect > to highlight the default button.)
