Selective lights erratic behavior

["Adrian Lopez" <liquidlightdigital(at)gmail.com>]

I've set up a light rig for a character, and tried to make the lights only light that character by moving the model into each lights associated model list.  Problem is, sometimes it works, sometimes doesnt - and at times it seems I have to switch the light from inclusive to exclusive and back to inclusive to see a change.  Other times, it renders transparent surfaces, like eyeball corneas, black.

Anyone else having this problem?
