Here you go.  This is how it loads.  As you can see, the texture image is loaded into the transparency window.  If I delete that and enter the correct transparency map, it changes back to the texture map immediately.  If I turn the transparency all the way down to 0, the correct transparency map will appear, but then of course the hair is completely invisible.  If I turn the transparency back up to anything more than 0, the texture map reappears in the transparency window.

If I remove the texture map althogether, the transparency maps appear in the transparency window and work fine, but now the hair has no texture.
