I am far from expert, but sounds... curious. Weird. Never encountered
anything like that myself. If you post the source, I might be able to help
you better. My best _guess_ is that there is some automatic vector
expansion going on, and by making it explicit in the macro you could avoid
the weirdness. Btw: what version of POV are you using?
