Chill haze can be caused by a number of different things... Not enough of a vigorous boil, not using Irish Moss or finings, cooling after the boil too slowly, etc... I would just check your process to make sure that you are doing everything right while making the batch to ensure that the final product is up to your standards.
Although chill haze may be annoying, it does not really affect the beer. IMHO, as long as the beer tastes good, forget about the chill haze. Just let it sit in the fridge for a while as an extended cold conditioning phase. May clear up just fine in a week or two. If not, who cares? It's a homebrew! Like I said, as long as it tastes good, you need not worry.
Oh yeah, you could also just serve it in a plastic cup or something that is non-transparent. It will be like the chill haze never existed! ;-)
