Strange text situation

I have text in all caps on a slide in my presentation.  I've synched it's animation, etc. and in all those windows, it appears exactly as I've typed it.  However, when I go to officially preview the slide through the preview button, it appears in all lower case.  This is the only slide in which I have text like that not appear as I have intended it.  Any idea as to why or how to fix that problem?  I guess it wouldn't matter if I knew for certain that when I upload this presentation for people to view that it plays with the look that I intend and expect it to have.
