No problem here if you do what Inside Macintosh really suggests: implement it as a UserItem. That is, install a separate UserItem in the dialog on top of the button to be highlighted. The UserItem has a bounding rectangle which is four pixels larger in each direction and a associated procedure which draws a three-pixel thick rounded rectangle inside the bounding rectangle. Updating the dialog window is then performed by ModalDialog or DialogSelect, when needed. >(Modal dialogs work OK). Not always true. If you put another dialog on top of your modal dialog, it will need updating when the dialog on top of it disappears. An example of this is calling SFGetFile from your dialog or Vaccine's own alert window. (* Johan Myreen *) (* jem@spica.hut.fi *)
