Blender Grass Problem

OKay so ive created my lovely grass

But when i add a wind element it goes ugly for some reason and the render looks awful

Please tell if this is a bug or careless mistake somewhere along the way
Here is the blend http://www.mediafire.com/?ma93juc3frf4983

could you post a screenshot?

The first is the good one and the second is the bad one with the wind element which hasnt been animated



It looks to me like the wind object is too narrow, so it is only affecting a narrow strip. Also, if you are using 2.5, you might want to add some noise to the ipo for the wind object.

Well that didnt exactly help if you look at the picture or blend file it almost appears as if some of the children disspear.
Is Hair dynamics required?
Is my lighting off?

yes i still need help
