Hi David,

A drop cap is simply a large character in a frame. I can duplicate the
effect you describe by selecting a paragraph containing a drop cap and
re-applying Normal style to it with Ctrl+Shift+N, which removes both the
frame and the large font size. So possibly something you did, or that Word
did behind your back while you did something else, applied Normal (or some
other style) to your paragraphs. I don't have any suggestions for what that
action might have been.
