Sounds good to me. Maybe #ifdef __WXMSW__ conditionally? I was just 
reading your earlier emails and tracing and baffled, so the fact that 
wxWidgets doc says it can happen makes me think we must do that 
workaround. I can confirm that making the Length button wxRB_SINGLE 
makes it not get loopy lost, but of course, it means programming the 
grouping behaviour, too.

So are you actually doing this in Win2K and still not seeing it in XP?

Thanks!
