-// VZ: the new behaviour is to create the radio buttons as children of the
-//     radiobox instead of creating them as children of the radiobox' parent.
+// there are two possible ways to create the radio buttons: either as children
+// of the radiobox or as siblings of it - allow playing with both variants for
+// now, eventually we will choose the best one for our purposes
+//
+// two main problems are the keyboard navigation inside the radiobox (arrows
+// should switch between buttons, not pass focus to the next control) and the
+// tooltips - a tooltip is associated with the radiobox itself, not the
+// children...

 //
 //

-//     This seems more logical, more consistent with what other frameworks do
-//     and allows tooltips to work with radioboxes, so there should be no
-//     reason to revert to the backward compatible behaviour - but I still
-//     leave this possibility just in case.
-#define RADIOBTN_PARENT_IS_RADIOBOX 1
+// the problems with setting this to 1:
+// a) Alt-<mnemonic of radiobox> isn't handled properly by IsDialogMessage()
+//    because it sets focus to the next control accepting it which is not a
+//    radio button but a radiobox sibling in this case - the only solution to
+//    this would be to handle Alt-<mnemonic> ourselves
+// b) the problems with setting radiobox colours under Win98/2K were reported
+//    but I couldn't reproduce it so I have no idea about what causes it
+//
+// the problems with setting this to 0:
+// a) the tooltips are not shown for the radiobox - possible solution: make
+//    TTM_WINDOWFROMPOS handling code in msw/tooltip.cpp work (easier said than
+//    done because I don't know why it doesn't work)
