Opposing spot lights render as black image.

Hello to all!

When using two spot lights, one 130 degree cone (at a 50 z-axis position) with a vector pointing directly out to the observer (to cast brilliant crystal highlights and semi-silhouettes), and one with a 45 degree cone pointed directly towards the objects in the same layer/scene from a 1000 z-axis position (to gently illuminate the front faces of the objects), the image renders black. Is this because algorithms cancel out the light affects? (...or... is this because I am not waiting for the rendering process to go longer than 10 minutes, and the lighting calculations take longer to develop visual results?)

Of course, if I turn off the opposing spot light, it renders fine (although not the complete effect I was looking to see).

Sincerely,
Clint.

Okay... like the age old solution of unplugging your device, waiting 10 seconds, and then re-powering the device to reset it and possibly solve any glitches present; I found out by closing the PS application and restarting PS, it solves this black render problem.    Weird...

Sincerely,
Clint.
