-   "Everything you ever wanted to know about the default buttons" or "Why do we
-   have to do all this?"
+   In normal Windows programs there is no need to handle default button
+   manually because this is taken care by the system provided you use
+   WM_NEXTDLGCTL and not just SetFocus() to switch focus betweeh the controls
+   (see http://blogs.msdn.com/oldnewthing/archive/2004/08/02/205624.aspx for
+   the full explanation why just calling SetFocus() is not enough).
+
+   However this only works if the window is a dialog, i.e. uses DefDlgProc(),
+   but not with plain windows using DefWindowProc() and we do want to have
+   default buttons inside frames as well, so we're forced to reimplement all
+   this logic ourselves. It would be great to avoid having to do this but using
+   DefDlgProc() for all the windows would almost certainly result in more
+   problems, we'd need to carefully filter messages and pass some of them to
+   DefWindowProc() and some of them to DefDlgProc() which looks dangerous (what
+   if the handling of some message changes in some Windows version?), so doing
+   this ourselves is probably a lesser evil.
+
+   Read the rest to learn everything you ever wanted to know about the default
+   buttons but were afraid to ask.
