about lights scale , and place highlights ...

[will_will]

I placed lights in scene, and scaled one , non-uniformly, a Sphere Light becomes Ellipsoid Light. then I tried use [Place Highlight] button , the light offsets far away ,and wrong direction.
I guess its a little glitch for 3ds max

My question is , should I use scaled light (specially non-unform scale) ? will they cause some rendering wrong or not ?
