40//
41//     For now I use an ugly workaround and process TTN_NEEDTEXT directly in
42//     radio button wnd proc - fixing TTM_WINDOWFROMPOINT code would be nice
43//     because it would then work for all controls, not only radioboxes but for
44//     now I don't understand what's wrong with it...
