I have no need for them and don't like having to constantly turn them off.
Okay, you obviously know where to turn them on and off so there's no point me talking about that but what comes to mind is that perhaps your templates are set up with these features activated by default and therefore every time you start a new part you are going to have that effect. If this is the case, check the templates, edit as necessary and then re-save them without the mirror (reflection) and shadow views activated.
I would spend some time looking threw the system options you could learn a lot there.
