1138 * Many. First, just what IS a frame in Win95? Note that the 3D look

1140 * edge. The inner rectangle just inside the frame is handled by the
1141 * Caption code.
1142 *
1143 * In short, for most people, this function should be a nop (unless
1144 * you LIKE thick borders in Win95/NT4.0 -- I've been working with
1145 * them lately, but just to get this code right). Even so, it doesn't
1146 * appear to be so. It's being worked on...
