wxWidgets/samples/dialogs/dialogs.cpp
Vadim Zeitlin c49245f8ba 1. added wxGetNumberFromUser (to textdlgg.cpp and dialogs sample) 
2. wxTE_RICH style added to wxMSW, the text controls don't use RICHEDIT
   class by default any more
3. wxRadioBox doesn't generate button events any more (grrr...)
4. commented out code in log.cpp restored and a bug corrected
