MASTER ANTONIO,,

lo quiero usar asi:: te explico::

en una ventana DEFINE WINDOW .... ACTIVATE WINDOW

este define tiene un BRUSH q es un tipo de formulario,, y desde recursos agrego los get para el llenado del mismo...

el SCROLL... no me funciona:: solo aparecen la barra pero no hace nada::

Ya hemos a帽adido la DATA bMouseWheel para la versi贸n 8.11, y efectivamente como indicas, lo id贸neo es soportar el scroll automaticamente sin necesidad de usar una clase adicional.
