LE FadeOut/In ISM problem

[LivewareCascade]

Hey guys, I've developed a sequence of ISMs that allow me to:

1.) FADEOUT - Fade from normal to black (animated, 3 sec duration)

2.) FADEHOLD - Black screen applied until FADEIN is called. (no animation)

3.) FADEIN - Fade from black to normal (animated, 3 sec duration)

This is all so the player can start a scripted sequence of events, sit in relative darkness which simulates the passage of time, and then have it fade back to normal once the script is all finished.

The problem is that the FADEOUT and FADEIN ISMs seem to fade to or from *white*, and I can't work out why. I know it's probably something really stupid, but could someone help me at all?

Here is a gallery showing the ISM data
The three ISMs are grouped in chronological order from left to right. The beginstate image shows the FIRST keyframes for each ISM, the Endstate image shows the LAST. This is so you can see what I'm fading from/to.

If it helps, here is the script used to control the ISMs:

    Function Fadeout()
    SessineISMFadeOut.Apply() ;fades to black
    Utility.Wait(2.5) ;the fade to black actually lasts 3 seconds, but I add the hold IMS early to prevent getting a flash of regular screen

    Function FadeIn()
    SessineISMFadeIn.Apply() ;fades back to normal

    EndFunction

Bugger, never mind. It's an ENB interfering.
