TFormSize will normally automatically load the persisted settings before the form‘s OnCreate event is triggered, so there is no chance to programmatically change the FormSize properties in code before the settings are loaded.

So, to achieve what you want to do, set FormSize.SavePosition = false & FormSize.SaveSize = false end then, in the form’s OnCreate event, first set FormSize.SaveName and after that, set FormSize.SavePosition = true & FormSize.SaveSize = true and then call FormSize.LoadFormSettings.
