White lines in transparentcies

I've got an alpha channel texture that's being rendered with white lines along the edges of the mask. I found the entry in the Trouble-shooting guide for TGE that says to turn off the tiling property of the diffuse map in Max's Material Editor. All that did was rest the tiling value to zero so my texture covered the entire model with a scaled up version of the texture and the lines were still visible.

So what am I not doing correctly? I'm unchecking the tile property of the UV's. Is there something else I should be doing? I'm using Max 8.

Thanks for any responses.
