Why to have map blop and no arrow?

[Spahut]

Its very useful to have the arrow pointing your way to the area. But once you are in the area I don't really need it pointing, but it would still be nice to have the area outlined on the minimap. However it seems when i turn of the arrow (by clicking on the blop in the quest menu) the highlight on the minimap goes away.

Isn't it possible to keep the highlight on the minimap and no the arrow (not that the pointing arrow should be removed, it's useful and will be needed a moment later)
