I seem to remember it being possible to uncheck that particular box in the past, or at the very least, it not being a default you can't alter. I've never really understood what use that option even might be, but then, possibly I've just never had a need for it to do so. In any event, I would really like to turn that option off, if it's even possible...

I see where this very question was asked last year, but there were no replies. Hopefully that changes this time...
