 110 // now, eventually we will choose the best one for our purposes
 111 //
 112 // two main problems are the keyboard navigation inside the radiobox (arrows
 113 // should switch between buttons, not pass focus to the next control) and the
 114 // tooltips - a tooltip is associated with the radiobox itself, not the
 115 // children...
 116 //
 117 // the problems with setting this to 1:
 118 // a) Alt-<mnemonic of radiobox> isn't handled properly by IsDialogMessage()
 119 //    because it sets focus to the next control accepting it which is not a
 120 //    radio button but a radiobox sibling in this case - the only solution to
 121 //    this would be to handle Alt-<mnemonic> ourselves
 122 // b) the problems with setting radiobox colours under Win98/2K were reported
 123 //    but I couldn't reproduce it so I have no idea about what causes it
 124 //
 125 // the problems with setting this to 0:
 126 // a) the tooltips are not shown for the radiobox - possible solution: make
