You cannot control the roundness of the RadForm's corners. By 'faint' I guess you are referring the corners in Q1 release. In Q2 2008, however, our RadForm is has the Office shape - the bottom corners are right angles, the top corners are round, and the borders are displaying pretty well.
Should you want to control the roundness of the corners, you can use our ShapedForm.
