Your feedback was very helpful. I think I now understand how the process works. The available presets in the Preset dialog page are taken from C:\Program Files\nLite\Presets\ rather than from the Windows Installation path which also has INI files. As you mentioned, you have to use the Preset button | Save to | LAST SESSION to update any changes to "C:\Program Files\nLite\Presets\LAST SESSION.ini" When I originally created the CD, nLite placed a "LAST SESSION.ini" file in the Windows Installation folder with the current Tweak settings. Since I did not Preset button | Save to | LAST SESSION, those settings were not saved to "C:\Program Files\nLite\Presets\LAST SESSION.ini" Therefore, one must be aware that INI files are saved at different locations and be aware of how those INI files are updated.
