I didn't get your answer wrong, no problem.

But I think you've by humour hit the right reason for the "problem" (don't think it's a bug). I just wanted to show that setting the two options to 0 is not just for freeloaders or that they can freeload anyway by unchecking the share box.

It's not a bad thing to set them to zero (at least if you're doing it temporarily) - it helps people find their files even if you are busy elsewhere.
