BUG: Check Boxes Always Appear Three-Dimensional (3D)

When the Appearance property of a check box is set to "0 - Flat," the check box always appears as three-dimensional or "1 - 3D." The backcolor of the check box still behaves normally when the Appearance property is set to "0 - Flat," and defaults to the window background color of the system.

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
