transparency issue in blender render with shading? Unsure how to fix this problem, just a generic fire in a fireplace, but the transparency isn't working correctly for some reason.

I'm in Blender Render. Not sure exactly what to search for to find the answer to this so I'm just asking.

Thanks, and I'm sorry if this is a repost of a previously asked question.
when using a transparency in Blender Render ensure that in the material tab , under options that the traceable box is unchecked so as to not cast a shadow on the transparent portion of the texture.
