1) Ah, I understand now. I guess it would make more sense to me if the
layout was more like this:
Scale mode: off/vector/scalar
Data to use: Normals/Your Data/Something else

But only data that makes sense in the selected scale mode is available.

Also - why is there no Shaft Length setting for the arrows?

2) ok, we'll see if anyone has any ideas.

Thanks,

David
