Toolset Question: Property Tab Buttons

Does anyone know how to keep the buttons closed after closing them, so that they do not reopen when you click on a new area object?

E.g. Properties window has “Appearance”, “Basics”, “Behaviour”, some of which I minimize by clicking the minus button. However, as soon as I select a new area object, they open again.

I would like to keep some permanently closed until I wish to open them.

I thought it may be to do with this file …
