One last thing to mention is the Overlay, is there anyway of creating an underlay like a coloured strip behind the writing.
This way if the camera has colour changes that cause the writing to be obscured with a transparency setting a colour could be applied to make sure the writing is always clear.

For the time being you could always use, the string "████████████████████" and past that in to Text 1 dialog, set font to lucida console, and make that a color, then in another dialog make your the text you want to put on top, with the same position, and a different color, thats how i got around the problem...
