1148 * Many. First, just what IS a frame in Win95? Note that the 3D look

1150 * edge. The inner rectangle just inside the frame is handled by the
1151 * Caption code.
1152 *
1153 * In short, for most people, this function should be a nop (unless
1154 * you LIKE thick borders in Win95/NT4.0 -- I've been working with
1155 * them lately, but just to get this code right). Even so, it doesn't
1156 * appear to be so. It's being worked on...
