I am having a problem with the gradient mesh tool in Illustrator CS. I create an object with a gradient mesh and export it as a swf file. When the swf is opened there is a white line round the object (this is evident when the object is against a background colour). Why is this happening? This was not the case in Illustrator 10. (I have had to go back to using Illustrator 10 to get the effect I want). Please would you provide an explanation of what I am doing wrong.

Thanks
