Grayed letters in display

Hi Chris,

Many, many thanks for the great work you've done and for making it available to all.

Yesterday I made a presentation for the church service this morning. I manually added a few songs and selected a fitting background. In the preview some of the letters did not show, and the letters that did show would show consistently. So for instance:
    Come Thou fount of every blessing
Would show as:
      o e o o nt o e e less g
The words would display OK on the lyricue-server display on the laptop. But just to be sure I tried on my 22" flat-screen and that showed OK too. So I thought it was just a glitch with the preview screens.

This morning to my dismay I found that all the letters that did not show on the preview would show grayed on the beamer / second monitor and all those that did show would show with their normal color on the beamer / second monitor. The same letters would be grayed across all the songs and announcements in the playlist.

I was using Lyricue version 2.3.1 but I tried the cvs2010080901 version and it has the same behavior (I haven't been able to get Lyricue 3 to run properly as to test if this had the same behavior). Any clues?
