Thanks. I've no idea what the problem is, but can you confirm that the 
workaround is to always supply an icon to wxMessageBox?

For example, adding a final 'else' in src/msw/msgdlg.cpp:

    if (wxStyle & wxICON_EXCLAMATION)
        msStyle |= MB_ICONEXCLAMATION;
    else if (wxStyle & wxICON_HAND)
        msStyle |= MB_ICONHAND;
    else if (wxStyle & wxICON_INFORMATION)
        msStyle |= MB_ICONINFORMATION;
    else if (wxStyle & wxICON_QUESTION)
        msStyle |= MB_ICONQUESTION;
    else
    {
        int majorVersion, minorVersion;
        wxGetOsVersion(& majorVersion, & minorVersion);

        if ( majorVersion >= 6 ) // Vista apparently requires an icon style
            msStyle |= MB_ICONINFORMATION;
    }

?

Thanks,

Julian
