Trouble with Faces

I've been doing work on my mod, and I've been having difficulties with the message faces. Here's the problem:

I'm scripting a conversation between Homestar(who I've made a face for already) and Mahin(who obviously doesn't have a message box face). Since I've got one with a message face and one without, I have to switch between FAC0027(Homestar's face) and FAC0000 (no face). But whenever I use the no-face, I have that big blank square spot in the message box. So my question is this: is there any way to get rid of that annoying blank spot?

 

The Big Blank Square is a result of false image formating or some fancy stuff.
The Upper left colour (for the square) should be 0 so r0g0b0 pure black

It is pure black.

 

it has to be the pallet's rendition of "invisible", whatever you set it at.

Nevermind, I got the blank square to disappear.
