[Qt-interest] QSettings never saves anything

[Matthias Pospiech]

If I want to use QSettings in its native OS way, I can never get the 
value after I saved it:

    SettingsFilename = "abc";
    QSettings settings;
    settings.setValue("SettingsFilename", SettingsFilename);

in different function:

    QSettings settings; // Native Settings of OS (not INI)
    filename = settings.value("SettingsFilename").toString();
 
then filename=="".

So from what I can see the value was nat successfully written or read or 
both.

What is the problem?
OS is WinXP SP3
