// VZ: normally, the trick with subclassing the tooltip control and processing
//     TTM_WINDOWFROMPOINT should work but, somehow, it doesn't. I leave the
//     code here for now (but it's not compiled) in case we need it later.
//
//     For now I use an ugly workaround and process TTN_NEEDTEXT directly in
//     radio button wnd proc - fixing TTM_WINDOWFROMPOINT code would be nice
//     because it would then work for all controls, not only radioboxes but for
//     now I don't understand what's wrong with it...
