I understand the resource acquisition....But the INI file created is completely
different for those two methods (should they be equal?). And the m_settings is
unable to read what it creates. The "value" always returns the default instead
of what's in the ini file.
Using m_settings to create the INI file, then using SettingsGroup to read it
works....it's just the m_settings that cannot read the value correctly..and
appears to have a problem reading other values too as many things seem to go
back to default.

Hi Mike, those are not equivalent. In what you call the "old" way the settings
group is closed just after setRxRange(m_fMin) but the so called "new" way only
closes the settings group when the SettingsGroup object instance goes out of
scope, which is the closing brace of the constructor. I suggest you look at the
implementation of SettingsGroup and do a bit of research on "Resource
Acquisition Is Initialization" (RAII) a.k.a. Execute Around. This is a
fundamental idiom in modern C++ for writing code with exception safety
guarantees when dealing with various resources.
