Holy shit. That is bizarre. I just tried it out in Microsoft Word 2001 and yes...the program prompts you to capitalize "Lucifer" (and all other proper names, I would assume, such as "Mary" or Bob or John...just tried Mary)...AND...get this: it prompts you to capitalize "Seeing Eye"....but not any other such pair of words.

Here is what I typed and how the program prompted the capitals:

I love god. I wonder about Lucifer. I also wonder about the Seeing Eye. Are Lucifer and the Seeing Eye connected?   What about Mary?

Here is the bouncing ball.

Here is the waving flag.

Here is the Seeing Eye.

The program takes no notice of "bouncing ball" or "waving flag" but it does insist on capitalizing "Seeing Eye".

Why?
